Product Description

Structural Steel Painting & Coating
Paint coatings for structural steelwork are usually spray applied. The paint is atomised into fine droplets and projected onto the surface to be protected where the droplets join together to form a continuous film. The atomisation can be accomplished in a number of ways.

 

Specification

Steel structure painting parameter

Parameter	Description	Typical Value	Notes
Surface Preparation	Cleaned surface (sandblasting/shot blasting)	Sa 2.5 (ISO 8501-1)	Removes rust and impurities
Paint Type	Coating material based on environment	Epoxy, Polyurethane, Zinc-Rich Primer	Enhances corrosion resistance
Coating Thickness	Uniform application for durability	100-150 microns	Adjust based on environment
Curing Time	Time allowed for drying/curing	4-8 hours per coat	Depends on paint type and conditions

Dimensions

Attribute	Description
Surface Roughness	Enhanced texture from sandblasting for optimal paint adhesion and durability.
Corrosion Resistance	Protective coating that prevents rust and withstands harsh environmental conditions.
Adhesion Strength	Strong bond between paint and surface, reducing risk of peeling and flaking over time.
Coating Thickness	Uniform paint layer, typically 100-150 microns, providing consistent coverage and protection.

Steel structure welding
Steel is used for ship hulls, offshore platforms, and docks because of its strength and durability in demanding environments.

Welded steel frames support large machines, cranes, and heavy-duty equipment that require solid and stable foundations.Welded steel frames support large machines, cranes, and heavy-duty equipment that require solid and stable foundations.

Features

1. High Strength and Load-Bearing Capacity
2. Uniform and Seamless Joints
3. Resistance to Environmental and Mechanical Stress

Applications of Steel Structure Welding
Given these features, steel structure welding is widely used in the construction of buildings, bridges, industrial facilities, shipbuilding, oil and gas infrastructure, and heavy equipment. The combination of strength, flexibility, and efficiency makes welded steel structures a core choice for modern engineering solutions.
