1.What are the differences in quality between different grades of color-coated steel plates?
Ordinary color steel plate: thin coating, average corrosion resistance, easy to rust in humid and rainy environment, lifespan is usually 5-8 years.
High-quality color steel plate: galvanized layer can enhance rust resistance, fluorocarbon coating has strong weather resistance (anti-ultraviolet, acid and alkali), lifespan can reach 10-15 years, or even longer.
Special material: excellent corrosion resistance, with advanced coating, lifespan can exceed 15 years, but the cost is higher.
2.What impact does the use environment have on lifespan?
Climate conditions: Long-term exposure to rainy, high humidity, coastal or industrial environments, rain, moisture, salt, and dust will accelerate coating aging and substrate corrosion, and the life span may be shortened by 30%-50%.
Sunlight intensity: Strong ultraviolet radiation can cause the coating to fade and crack, especially in tropical or highland areas, which may affect the service life.
3.How does installation and maintenance affect service life?
Installation process: If the joints of the panels are not properly treated during installation and the fixings are not rust-proofed, rainwater can easily penetrate into the interior and cause the substrate to rust, which will greatly shorten the service life.
Daily maintenance: Regularly clean the surface dust, fallen leaves and other debris, and repair the coating in time if it is damaged, which can extend the service life by 1-3 years.
4.What should be paid attention to when building a color steel canopy?
The core of the construction of color steel plate canopy is "leak-proof, wind-resistant, and rust-proof". Every step from material selection to construction details must be strictly controlled, with special attention paid to sealing and fixing processes. Standardized construction can greatly reduce the cost of later maintenance and extend the service life of the canopy to more than 10 years.
5.How to extend the service life?
Edge and corner treatment
The edges of the color steel plate need to be wrapped with special edge strips to prevent the rough edges of the plate from scratching people and prevent rainwater from seeping into the substrate from the cut.
The corners need to be rounded or sloped to reduce water accumulation and stress concentration.
