Are EPDM washers reusable?

No, EPDM washers should not be reused once compressed, as their sealing property is compromised after initial installation.

Are EPDM washers heat-resistant?

Yes, they are designed to withstand high temperatures and extreme conditions.

Can J-Bolts and L-Bolts be used on all roofing sheets?

Yes, they are designed to anchor both round and square pipes to all types of roofing sheets.

What size should the holes be for J-Bolts and L-Bolts?

The hole size should be at least 3 mm larger than the bolt diameter for proper fitting.

What is an EPDM washer and how does it prevent roof leaks?

An EPDM washer seals around screws and fasteners, creating a watertight barrier that stops leaks and protects the roof from water damage.

Can I reuse EPDM washers on my roof screws?

No, EPDM washers lose their sealing power after first use, so reusing them can cause leaks and roof damage.

Are EPDM washers resistant to heat and extreme weather?

Yes, EPDM washers are engineered to withstand high temperatures and harsh conditions without losing their sealing ability.

Can I use J-Bolts and L-Bolts on any roof sheet?

Yes, J-Bolts and L-Bolts work with all types of roofing sheets to securely fix round or square pipes without damaging the roof.

What is the correct hole size for J-Bolts and L-Bolts?

Use a hole slightly larger than the bolt - around 3 mm extra - to allow proper alignment and tight installation.
