Description
Corrosion resistant powder coated C steel starts with cold-formed C-section steel as the base material. The steel goes through rust removal, degreasing and phosphating. Then powder spraying and high-temperature curing form a protective coating on the surface.
Product Feature
The coating resists acid, alkali and moisture.
Surface adhesion stays strong under normal use.
Section height and wall thickness follow standard C purlin dimensions for load-bearing needs.
Main Applications
Chemical plants, sewage treatment stations, coastal buildings, food processing factories, warehouses, and other structures that face corrosion risks.

Product Advantages
Corrosion resistant powder coated C steel holds up in wet or chemically rough conditions. The coating does not peel easily, so the steel underneath stays protected longer. That means fewer repairs over the life of the building.

FAQ
Q1: Is this the same as regular powder coated C purlin?
A1: It uses the same base material and coating process. The difference is the coating formulation is tuned for better resistance against acids and alkalis.
Q2: Does the color fade over time?
A2: The powder coat holds color well under normal daylight. In areas with strong UV, we suggest adding UV-resistant top coat if color matching is critical.
Q3: How do I clean the surface?
A3: Regular water washing or mild detergent works. Avoid strong acid or alkaline cleaners, as they may slowly wear the coating over many years.
