Hot-Dip Galvanizing · Fabrication · Karachi, Pakistan
Industrial Sheds & Structures
Portal frames, trusses, purlins and complete pre-engineered shed structures — designed, fabricated, hot-dip galvanized and supplied as a design-to-erection package.
Overview
An industrial shed is a 30-year asset, and the frame is the part you cannot replace cheaply. We engineer the structure for your span, eave height, roof load and wind zone, fabricate every member in our bay, and hot-dip galvanize the entire frame so it stands up to Karachi's humidity, salt air and industrial atmosphere.
Our packages run from design through fabrication, galvanizing, cladding supply and erection supervision. Frames arrive on site as numbered, bolt-together kits — every member already coated, every connection plate drilled, and every fastener galvanized per ASTM A153.

Galvanizing Process Notes
Shed frames are made of bolted sub-assemblies by design — each sub-assembly fits the kettle, galvanizes cleanly, and bolts together on site with no welding. This is why a galvanized pre-engineered building erects in days, not months, and why the frame will still be sound when the cladding is replaced decades later.
Why Karachi Galvanizing?
