FAQS

Frequently Asked Questions

Technical guidance on selecting and installing the correct fasteners for your facade project.

What is the maximum drilling capacity of these screws?
Depending on the screw size, they can typically penetrate steel or aluminum thicknesses ranging from 1.5mm to 12mm.
Are these screws suitable for coastal environments?
Yes, for coastal projects we recommend our SS316 or specialized anti-corrosion coated versions to ensure maximum durability.
Do I need to pre-drill holes for M4.8 screws?
No, these are self-drilling/self-tapping screws designed to create their own pilot hole and thread in a single operation.
Can the screw heads be color-matched to the facade?
Yes, we provide custom powder-coating services to match the screw heads to any RAL color used in your aluminum panels.
What standards do your fasteners comply with?
Our screws are manufactured in accordance with DIN, ISO, and GB standards to ensure consistent quality and performance.
