Coating of Large Welded Structural Components

We offer a variety of coating processes, including hot-dip galvanizing, thermal spray zinc, and painting, to meet different protection and decorative needs:

Hot-Dip Galvanizing:

• Process: Steel components are immersed in molten zinc to form a strong zinc-iron alloy layer + a pure zinc layer.

• Core Advantages: Extremely long protection life (typically 20-50 years), strong metallurgical bonding adhesion, comprehensive coverage with no dead angles, and excellent cathodic protection (sacrificial anode).

Thermal Spray Zinc:

• Process: Zinc material is melted by flame/electric arc and sprayed at high speed onto the surface to form a coating (often supplemented with sealants).

• Core Advantages: Flexible construction without size limitations (especially suitable for large on-site components), no risk of thermal deformation of the substrate, precise control of coating thickness, and reliable cathodic protection.

Painting:

• Process: Primer, intermediate paint, and topcoat are atomized and sprayed to form a multifunctional coating system.

• Core Advantages: Offers an extremely rich selection of colors and gloss, outstanding decorative quality, flexibility to adapt to complex shapes, and the ability to achieve diverse functions such as high weather resistance, UV resistance, fireproofing, and chemical resistance through coating combinations.

We can recommend and implement the most suitable coating solutions based on the project's required protection lifespan, component characteristics (size, shape, location), aesthetic needs, and budget.
