Surface treatment Options
Hot-Dip Galvanized Scaffolding
Hot-dip gi scaffolding is achieved by fully immersing steel components into molten zinc, which have a thick and durable zinc layer. This treatment performs well in corrosion resistance.
Application: It's suitable for outdoor, coastal, or humid construction environments, ensuring long service life.
Electro Galvanized Scaffolding
Electro galvanizing offers a thin zinc coating by electroplating process.While the corrosion protection is limited compared to hot-dip gi scaffold, but the surface is smooth and price is cheaper.
Application: It's suitable for indoor or short-term projects.
Powder Coated Scaffolding
Powder coating spray resin-based powder onto the scaffold surface, and creates a uniform, wear-resistant coating. It's durable and long service life.
Application: It's suitable for outdoor environment.
Painted Scaffolding
Painted scaffolding is a basic protective paint layer on the frame surface. It have more color selections and cheaper price, but the corrosion and resistance is not as good as galvanized or powder-coated finishes.
Application: It's suitable for indoor or short-term projects.
