Associated Lead Mills and JMR Hard Metals endeavour to deliver all materials using our own team of drivers and fleet of vehicles.
No matter how big or small the order, JMR can deliver using any of the several trucks we run on a daily basis. Our trucks can deliver anything from 1 metal sheet to 20+tons in coil with HIAB Crane Offload available upon request. We also run small trucks to cater for awkward site access and small order deliveries.
Once a contract is placed for large order quantities, JMR will hold the stock in our secure premises and allow the customer to “call off” material as and when required. Invoices are only raised upon delivery so providing the customer initially secures their order with a contract, we will hold the price set by the contract preventing any effects the London Metal Exchange may have on the metals worth.
Following strict assessment, JMR’s whole transport department has been awarded FORS accreditation.
FORS is a method of recognising fleet operations which comply with the requirements of the FORS standard. The FORS standard is based upon lawfulness, safety, efficiency, and environmental protection.
FORS is a voluntary certification scheme aimed at ensuring that fleet operators work lawfully and to best practice as stated in the FORS standard. This standard allows JMRs fleet to carry out deliveries on certain sites and in certain locations where non registered carriers cannot
JMR meets the criteria set out in the FORS standards following a company audit which took place on our premises and was carried out buy an independent FORS auditor.
Order collection is also possible from either of our two Hoddesdon based warehouses.
Associated Lead Mills are the main sponsor for the Murdoch Awards.
The Murdoch Awards is the ultimate accolade for any lead worker confident enough to put their projects forward allowing their workmanship and abilities to come under the scrutiny of judges and peers.
With regard to associations, JMR are members of all governing bodies ensuring that as a distributor to the UK industry, we are kept up to date with details and information that could affect our customers which include installers, fabricators, architects and main contractors.
We are pleased to be members and associate members of the following.
Lead
The LCA (Lead Contractors Association)
Lead and Hard Metals
The NFRC (National Federation of Roofing Contractors)
The CRC (Confederation of Roofing Contractors)
Hard Metals
The FTMRC (Federation of Traditional Metal Roofing Contractors)
NBS Specifications for all Rolled Lead roofing, cladding, flashing and penetration. If you experience problems, please feel free to request via email or phone and an JMR representative will be happy to forward arrange. All users should be aware when using any materials that getting the specification right first time is an essential part of the design process.
Failure to form a clear specification will cause major problems for all those involved in the build potentially causing on site chaos. This can reflect badly on those involved costing the main contractor and / or the client potential loss of revenue. A well written specification can only enhance project delivery which in turn saves money for all involved.
General
Our products, made out of copper or copper alloys, have natural or nature identical surfaces that will continuously develop and react upon atmospheric influences. The special manufacturing technology used allows colour variation in the individual sheets/coils. Furthermore, variations within the development of the sheets/coils in outdoor weathering and ambience conditions are possible and do not constitute a defect.
The products made out of TECU ® copper or copper alloys, like TECU ® Patina, TECU ® Iron, TECU ® Oxid, TECU ® Zinn, TECU ® Brass, TECU ® Bronze and TECU ® Gold, are special products, in parts exclusively produced upon customer request. We herewith point out that, in the event of possible re-orders / subsequent deliveries, the new production will take a specific period according to the respective production time, most likely, cannot be effected immediately and can also be liable to minimum quantities.
Protective film (Brass & Gold)
The film covering is designed to protect the surface of sheet or coil material during fabrication/processing and installation.
It must be removed as soon as possible after installation, especially when exposed to external weathering and UV radiation (sunlight).
This protective film is only a temporary covering. Avoid a storage time longer than 3 months. Foiled copper or copper alloys have to be stocked in conditioned rooms.
Please remove the film with care and check the metal surface for potential adhesive residues. Any adhesive residues must be removed with care (e.g. Acetone swab) to permit normal weathering.
TECU ® Patina
Variations of the color:
Delivered TECU Patina sheets can have variations in color. Within a single sheets color from light green to blue green are possible. These variations, found after production, within single sheets, adjust within a few weeks by themselves and are dependent on weather conditions and building situation. TECU Patina sheets which are installed in an area protected from rainfall will require a longer time for the development. An interior application of TECU Patina should be discussed with the KME-Team because the development may take a very long time. Each single sheet is unique and may develop itself individually.

Furthermore variations within the development of the sheets in outdoor weathering and ambience conditions are possible and do not constitute a defect.
The products made out of TECU(R) copper or copper alloys like TECU®- Patina, TECU®-Iron, TECU®- Oxid, TECU®-Zinn, TECU®-Brass, TECU®- Bronze and TECU®-Gold are special products, in parts exclusively produced upon customer request. We herewith point out that in the event of possible reorders / subsequent deliveries, the further production will take a specific period according to the respective production time and most likely cannot be effected immediately and can also be liable to minimum quantities.
TECU Patina Hamburg, Boston, Madrid and Oslo
Deviations of the surface appearance: Delivered TECU Patina Hamburg, Boston, Madrid and Oslo sheets can have deviations in their appearance, within single sheets, from sheet to sheet or from delivery to delivery. Also the appearance of the delivered sheets may differ to samples which were presented. As known for the TECU Patina, also these TECU Patina variations will develop across their surfaces in relation to the building location, prevailing weather conditions and the atmosphere. Each single sheet is unique and may develop itself individually.
In case of planned internal application we urgently ask you to contact the KME Team before your order.

Perforated
Guarantee: The perforating process impacts significantly on the sheet surface.
Return / Exchange: As the material has been produced ‘to order’ and is bespoke, we cannot accept any material return / exchange. For the same reasons, it is not possible to supply small top-up amounts after the main order.
Tolerances:
The usual tolerances for perforated sheet apply. On request, we can specify these more closely.
Please note that the manufacturing process may cause a wider tolerance on the supply quantity of finished material than usual, therefore the supplied quantity of finished material may be more or less than stipulated. Please allow for this in your calculations.
Classic Coated
TECU® Classic_Coated consists of Cu-DHP Copper, according to the standard EN 1172 and shows a typical copper rolled surface. Through the “coil coating” process, a transparent coating is applied to the copper surface, which protects the surface against natural weathering.
Production-related colour variations of the rolled mill finished copper surfaces are possible and do not constitute a defect or quality deficiencies.
TECU® Classic_Coated is a bespoke product, which is produced to customer requirements. “Top-ups” or subsequent deliveries will be subject to production lead-times, minimum order quantities and lot sizes.
The temporary protective plastic film is designed to protect the surface of the sheet / coil material during fabrication / processing and installation. It must be removed as soon as possible after installation, especially when exposed to external weathering and UV radiation (sunlight).
Please remove the temporary protective plastic film with care and check the metal surface for potential adhesive residues. Any adhesive residues can be removed with care using an appropriate cleaning agent e.g. Acetone.
It is essential to follow the processing and application instructions found inside the packing unit, provided by KME.
TECU ® Iron one and two
Delivered TECU Iron one and two sheets can have deviations in their appearance, within single sheets, from sheet to sheet or from delivery to delivery. Also the appearance of the delivered sheets may differ to samples which were presented. These sheets will develop across their surfaces in relation to the building location, prevailing weather conditions and the atmosphere. Each single sheet is unique and may develop itself individually.
In case of planned internal application we urgently ask you to contact the KME Team before your order.
The products made out of TECU(R) copper or copper alloys like TECU®- Patina, TECU®- Iron,
TECU®-Oxid, TECU®- Zinn, TECU®-Brass, TECU®-Bronze and TECU®-Gold are special products, in parts exclusively produced upon customer request. We herewith point out that in the event of possible reorders / subsequent deliveries, the further production will take a specific period according to the respective production time and most likely cannot be effected immediately and can also be liable to minimum quantities.
Treated surfaces
The products made out of TECU ® copper or copper alloys like, TECU ® Brass Artisan, are special products, in parts exclusively produced upon customer request. It is to be expected that there is variation across this surface and will develop with natural weathering. We herewith point out that in the event of possible re-orders / subsequent deliveries, the further production will take a specific period according to the respective production time and most likely cannot be affected immediately and can also be liable to minimum.
Brass Brownished
TECU® Brass_brownished consists of Brass CuZn30 according to the standard EN 1652 and shows a typical rolled surface, which is burnished (brownished) in an industrial process.
Surface
We expressly declare that due to the production process we do not guarantee for a consistent stable and unchangeable surface. Production-related surface and colour variations like clouds, cords and streaks on the finished brownished Brass surfaces are possible and do not constitute a defect or quality deficiencies. In principle it is to be expected that colour variations can occur during the brownishing process. A production is carried out on the basis of the condition of a prior sampling and written confirmation.
Claims
A claim can only be accepted 5 days after delivery. We therefore kindly request your prompt goods inwards inspection.
Preservation
After the brownishing process the surface is treated with a temporary wax fluid, which is necessary for the preservation of the surface.
The consistently application of the wax fluid is to be checked during the installation work. Eventually using a soft cloth the wax fluid needs to be evenly spread or renewed under consideration of the surface’s grinding direction (linear or circular grinding).
If required the wax fluid can be removed and applied completely new. The preservation avoids or rather slows down the weathering process. By the building owner the preservation should be considered within the planned provide cleaning intervals.
Please note this wax fluid continuously weathers off and the natural weathering process of the TECU® Brass_brownished surface starts.
Processing
TECU® Brass_brownished surfaces are factory-refined and should be handled and processed with special care.
After installation in coastal regions, TECU® Brass_brownished surfaces may show a varying weathering behavior.
TECU® Brass_brownished is a bespoke product, which is produced to customer requirements. “Top-ups” or subsequent deliveries will be subject to production lead-times, minimum order quantities and lot sizes.
It is essential to follow the processing and application instructions found inside the packing unit, provided by KME.

The Truth About Lead is a video in which all the misconceptions of lead are answered. Lead is one of the oldest materials used in building and has been trusted to shelter monumental constructions that were, and in some cases still are, our most important buildings. Stately Homes, Court Houses, Churches, Catherdrals and Palaces all utilised lead as a roofing material due to its availability, low maintenance requirement and longevity.
Lead for many years has been used in some form on every building. In more recent times, lead has been wrongly attributed as a product that doesnt meet modern environmental requirements. Although when looking deeper into the source, it normally stems from an alternative product that’s simply looking to take some of the lead market for its own replacement product, which claims to be greener, yet in a life cycle test will simply fall flat when compared to the performance of lead. In this video, you will hear the argument for lead rather than against and will be pleasantly surprised by how green the material actually is!

Helpful to the architect specifier, the builder’s merchant and the end user, the comprehensive Rolled Lead Sheet and Flashing Theoretical Weight Chart gives all rolled lead weights. It gives the weight of all our rolled lead, by code/thickness, for all different widths and lengths available direct from stock. The weights are given in kilos per roll and kilos per square metre, according to width and length required and includes a helpful comparison to the nearest imperial inch.
All theory weights are subject to EN 12588:2006 (manufacturing tolerance of +/- 5%), and calculated by: length (m) x width (m) x KG/m2
JMR can also offer bespoke width and length rolls upon request.
To further assist our customers when using JMR products, we offer the Craftsman’s Guide which contains a collection of helpful details and information on the premium roofing products range such as; Flashpoint. Lead Restorers, Expansion Joints, Wood Cored Batten Rolls, Fixing Clips and Strip, Lead Dome Sets, Annular Ring Shank Nails, Underlays, Flexislates, Hall Clips, Metwash, Patination oil, Lead Slates, Fluxes and solders.
Flashpoint provides a preferred alternative to the use of mortar as a pointing material for lead-brick and lead-masonry joints. Mortar is unable to expand and contract with lead and masonry during temperature variations, leading in some cases to the mortar cracking and allowing ingress of water.
Flashpoint is a one part, neutral cure, silicone based sealant that once applied will cure to give a flexible, durable and elastic seal, capable of accommodating the high degree of thermal expansion and contraction often encountered with lead flashings exposed to direct sunlight.
Because of its water content, mortar cannot be applied in cold, frosty conditions. However, Premium Flashpoint with its large service temperature range can be used at temperatures down to -65 C.
Our range of soft solders include Plumbers ‘D’ and Tinman’s Solder.
Our range of fluxes include Zinn7, ZD-Pro, Deca-Quartz, Soldering Gel.
Call for additional information
