Keguan Coatings Steel Structure Coatings, Steel Structure Paint Manufacturer (Paint Product Consultation 152_0825_6966 Manager Sun) Steel structure paint contains anti-rust pigments, resins, and other components, which can form a dense protective film on the steel surface, preventing oxygen and moisture from contacting the steel, thereby preventing rust and corrosion.
Steel structure paint can resist the effects of natural factors such as ultraviolet radiation, temperature changes, and wind and sand erosion. High-quality steel structure paint will not fade, chalk, or crack after long-term exposure outdoors.
Steel structure paint is available in a variety of colors and finishes, such as matte, semi-gloss, and high gloss. Depending on architectural design requirements, steel structures can be painted in different colors to enhance the building's appearance.
Steel structure paint adheres firmly to the steel surface, which is key to ensuring its protective and decorative functions. It bonds with the steel surface through chemical bonding, physical adsorption, and other methods.
Steel structure paint generally has good fluidity and workability, making it easy to apply using brushing, spraying, rolling, and other application methods. Moreover, under appropriate construction conditions, the paint layer dries at a moderate speed, neither too fast nor too slow.

Construction Environment
The temperature is generally recommended to be between 5 - 35°C. If the temperature is too low, the paint will dry slowly or may not dry at all; if the temperature is too high, the paint may dry too quickly, leading to poor coating quality, such as orange peel or cracking. Humidity is also important, and generally should not exceed 85%. In high-humidity environments, moisture in the paint may not evaporate easily, causing issues such as whitening or blistering.

The coating thickness of steel structure paint varies depending on usage requirements and the type of paint. The primer thickness may be around 50 - 70μm, the intermediate coat around 70 - 100μm, and the topcoat around 30 - 50μm. A dry film thickness gauge can be used to measure the coating thickness, ensuring it is uniform and meets requirements. If the coating is too thin, it may not provide adequate protection and decoration; if it is too thick, quality issues such as cracking or peeling may occur.
