Premium industrial fasteners (SDS) with specialized coatings for lifetime corrosion protection on metal roofs. Serving Kolkata's Jute processing sector with authorized brand supply and custom project dispatch.
Kolkata is East India's industrial gateway, anchored by Haldia's deep-water port, a massive jute and leather processing industry, and the Dankuni industrial complex. The city's extreme monsoon climate — with some of India's highest annual rainfall — creates unique roofing challenges that require deep-profile trapezoidal sheets with high-AZ coating and precisely designed drainage gradients. Apex Metals supplies monsoon-engineered roofing solutions for Kolkata's demanding climate and diverse industrial base.

We provide specialized delivery and on-site technical support across all major industrial clusters in the Kolkata region, including:
As part of the West Bengal industrial landscape, Kolkata plays a vital role in the region's manufacturing output. The state's push for infrastructure development, including new expressways and industrial corridors, has led to a surge in demand for sustainable and high-durability construction materials like self drilling screws.
Apex Metals supports the West Bengal Industrial Development Corporation initiatives by providing materials that meet and exceed local building codes. Whether your project is in a government-allocated industrial area or a private logistics park in Kolkata, our supply chain is optimized to ensure zero delays.
Selecting the right grade of Self Drilling Screws in Kolkata requires a deep understanding of local environmental stressors. Kolkata's extreme monsoon (annual rainfall 1,700mm+) and high humidity year-round demand mandatory roof drainage design with deep-profile sheets and sealed overlaps. Coastal proximity at Haldia requires AZ150+ Galvalume. At Apex Metals, we don't just supply material; we provide engineered solutions optimized for the West Bengal region.
For industrial projects within the Dankuni Industrial Complex and surrounding areas, our Self Drilling Screws features a high-performance metallic coating (AZ150/AZ200) that acts as a sacrificial barrier against oxidation. This is particularly critical in Kolkata where extreme temperature fluctuations can accelerate traditional steel degradation.
Moreover, the structural integrity of our Self Drilling Screws is verified through rigorous testing for wind-load resistance, a crucial factor for the open industrial belts around Kolkata. Our technical consultants can provide specific thickness recommendations (0.45mm to 0.60mm) depending on the truss spacing and local wind speeds in West Bengal.
Apex Metals operates a streamlined logistics network connecting our central Hisar hub to major industrial sites in Kolkata. We leverage major national highway networks to ensure that your bulk orders of Self Drilling Screws reach your site within 6–8 business days from Hisar hub to Kolkata via rail freight.
Our fleet is equipped to handle long-length Self Drilling Screws deliveries (up to 12 meters) directly to project sites in Dankuni Industrial Complex, Haldia Port Zone, Salt Lake Sector V IT Hub, Maheshtala Industrial Area. For large-scale developments in the West Bengal corridor, we offer dedicated vehicle placement, reducing transit time and minimizing handling risks.

Every batch of Self Drilling Screws supplied to Kolkata is accompanied by a Mill Test Certificate (MTC). We ensure that the steel base, aluminum-zinc coating mass, and paint thickness (micron count) meet the exact BIS standards required for institutional tenders and industrial approvals in the West Bengal region.
Using advanced CNC profiling machines, we ensure that every Self Drilling Screws sheet has consistent rib depth and overlap width. For projects in Dankuni Industrial Complex, this precision ensures a 100% weather-tight seal, protecting your sensitive machinery and inventory from West Bengal's monsoon and dust storms.
