Epoxy-Coated Self Drilling Screws – RX Screws for Metal Roofing in Mumbai, Navi Mumbai, Panvel & Thane

When it comes to fixing metal roofing sheets, the quality of fasteners is just as critical as the sheet itself. At Acier Steel Pvt Ltd, we offer high-performance RX brand epoxy-coated self drilling screws designed specifically for roofing, cladding, and structural steel applications. Available across Mumbai, Navi Mumbai, Panvel, and Thane, these screws offer superior performance, faster installation, and longer life compared to conventional GI screws.

Why Choose Epoxy-Coated Self Drilling Screws Over Traditional GI Screws? ✅ 1. No Pre-Drilling Required

Traditional GI screws require pre-drilling, increasing labour time and risk of misalignment. RX self drilling screws come with an integrated drill point that pierces through steel up to 12 mm thick, reducing installation time by over 50%.

✅ 2. Epoxy Coating for Corrosion Resistance

The epoxy coating provides a durable barrier against corrosion, especially in coastal regions like Navi Mumbai and Panvel, where humidity and salt can degrade standard fasteners quickly. Unlike basic GI screws that rust over time, epoxy-coated screws offer long-term durability and better aesthetics.

✅ 3. Weather Tight Sealing with Washers

Each screw is equipped with a bonded EPDM washer, ensuring a watertight seal between the metal roofing sheet and the screw. This eliminates leakage points – a common problem when using unsealed or loose-fitting GI screws.

✅ 4. Stronger Grip with Precision Threads

RX Screws come with 12G diameter and fine threads (14 or 24 TPI) which offer higher holding strength, essential for high wind-load areas like Thane and Mumbai coastal zones.

✅ 5. Reduced Roof Vibrations & Loosening

Conventional GI screws are more prone to loosening over time due to thermal expansion and vibrations. Self drilling screws, with their tight fit and higher torque holding, stay firm longer, reducing maintenance needs and risks of roof damage.
