Product Description
Hot dip galvanized steel structure fabrication provides superior corrosion protection for outdoor steel buildings and equipment. We fabricate steel structures and apply hot dip galvanizing according to customer specifications.
Hot Dip Galvanizing Process
Hot dip galvanizing involves immersing steel workpieces in molten zinc at optimal temperatures. The zinc penetrates the steel surface to form a durable zinc-iron alloy layer. This metallurgical bond creates an exceptionally strong, dense protective coating suitable for diverse steel products.
Our Manufacturing Facility
Our factory features three dedicated steel structure production lines equipped with:
- Flame cutting machines
- H-Section steel assembly machines
- Gantry welding machines
- Shot-blasting machines
- Paint spray booths
We maintain specialized workshop space for fabricating heavy-duty and large structural steel components.
