Can Apex Engineers match any RAL colour for plastic screw caps?
Yes. We pigment-match the polymer batch to any RAL Classic shade before moulding — including RAL 9002, 5012, 3000, 6011, 7035 and 8017 — or match directly to a roofing sheet sample you send.
Why should screw caps match the roofing sheet RAL colour?
Colour-matched caps make the hundreds of fasteners on a roof visually disappear, giving a clean architectural finish. Mismatched or bare screw heads create a spotted look and, once rusting starts, dark streaks down the sheet.
Do RAL colour caps fade in the sun?
Our caps are moulded from UV-stabilized compounds, so the shade resists fading and the cap resists cracking through years of direct sun and monsoon exposure.
What is the MOQ for a custom RAL colour cap?
Custom RAL shades run as dedicated batches, so they carry a higher MOQ than standard colours. Call +91 6352894037 with your RAL code and quantity for exact MOQ and pricing.
