What is the best material for door sweeps for large gaps?

For general industrial use, EPDM is ideal. For extreme temperatures, silicone is recommended due to its superior thermal stability.

Can you provide custom profiles for irregular gaps?

Yes, we offer custom molding services. You can provide a technical drawing, and we will create a tailored profile to fit your specific gap.

How do I measure my door for a large gap sweep?

Measure the widest part of the gap from the bottom of the door to the floor. We recommend adding 2-3mm for a tight compression seal.

What is the average lifespan of these rubber seals?

Depending on traffic and material, our industrial sweeps typically last between 5 to 10 years before needing replacement.

Do you offer wholesale pricing for large projects?

Yes, we provide tiered pricing for volume orders, specifically for warehouse renovations and construction projects.

How do these sweeps handle heavy equipment wheels?

Our high-density rubber is designed for resilience. It compresses under load and returns to its original shape without permanent deformation.
