Metal roofing fasteners- Add value to your investment

Metal roofing fasteners

Whether your roof is a roof panel or a standing seam roof panel, it will have some exposed fasteners. The fasteners, therefore, must be durable to prevent perforation of the roof panels. A non-durable fastener will always begin to rust, even if painted. Avoid this by always using long-lasting fasteners in all exposed fastener locations. Failure to adhere to this could reduce the service life of your roof.

A fastener must be able to withstand all the environmental elements it is exposed to. These include UV degradation, salts from marine environments, acid from industrial pollution, rain, extreme heat, fumes and gases from within factories and plants, etc. While exposed to these conditions the washers must remain elastic, intact and watertight for the life span of the complete roofing system.

Fastener cost less than 3% of the Cost of the building & less than 1% of the cost of the total project. Yet, we see that people want to compromise of the Quality of such small item having such huge significance on the Sustainability of the Building. Therefore, it is always preferable to go for a proven expert for fastener works. One such group is Realm India.

Realm’s Roofing self drilling fasteners meet the RoHS Compliance Definition.The definition and aim of the RoHS directive is quite simple. The RoHS directive aims to restrict certain dangerous substances commonly used in electronic and electronic equipment. Any RoHS compliant component is tested for the presence of Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent chromium (Hex-Cr), Polybrominated biphenyls (PBB), and Polybrominated diphenyl ethers (PBDE). For Cadmium and Hexavalent chromium, there must be less than 0.01% of the substance by weight at raw homogeneous materials level. For Lead, PBB, and PBDE, there must be no more than 0.1% of the material, when calculated by weight at raw homogeneous materials. Any RoHS compliant component must have 100 ppm or less of mercury and the mercury must not have been intentionally added to the component. In the EU, some military and medical equipment are exempt from RoHS compliance.

This thermoset membrane is compound from rubber polymer and is often referred to as rubber roofing. The American Society for Testing and materials (ASTM) classifies this material as an M Class Polymer. Ethylene and propylene derived from oil and natural gas, are organic building blocks of EPDM. When combined with diene to from the basic rubber matrix, the result is long-chain hydrocarbon with a backbone of saturated molecules and pendant double bonds. The Practical translation is ethylene, propylene and diene combine to form a large molecule that is very stable when exposed to sunlight, heat, ozone (UV) and moisture.

EPDM (Ethylene Propylene Dine Monomer) became the seal of choice with the leading roof fastener manufacturers. This terpolymer elastomer is particularly well suited for sealing washers due to its resistance to water, chlorinated water, dilute acids, alkaline, ozone and oxidizing chemicals. It has a negligible absorption rate, is not susceptible to swelling, and can withstand temperatures up to 100°C

Conclusion

It is important to realise that high heat affects tear strength. With 4.5 fasteners per square metre of roofing sheet, washers play a significant role in any roofing project. Realm recommends that consumers ensure that the washer they purchase complies with industry standards and supports the life and integrity of the roofing system.  The right balance of hardness, tear strength and compression performance determine how well a cut washer assembles, compresses and resists the tearing effects of swarf, and keeps the screw sealed throughout its life on the roof.
