Product Core Introduction
The orange-yellow pre-coated color steel plate is mainly in the warm and vibrant orange-yellow color. It adopts a zinc-aluminum-magnesium alloy substrate with a modified polyester coating. The zinc-aluminum-magnesium coating comes with a self-repairing passivation film, and its anti-corrosion capacity is twice that of ordinary galvanized steel plate. The coating adopts a low-saturation warm color formula to avoid the problem of bright yellow being harsh, while taking into account the warm texture and dirt resistance. The board has high flatness, a matte and soft surface effect, and no strong reflections. It is suitable for various architectural scenes that require a soft visual atmosphere and supports secondary processing such as cold bending, tile pressing, and edge folding.

Adapt to usage scenarios (solve the pain points of scenario matching)
The core is adapted to the facades of school teaching buildings, kindergarten parks, elderly care supporting buildings, warehousing and logistics factories, agricultural and breeding sheds, and small street-facing shops. The warm orange-yellow hue can weaken the cold feeling of industrial buildings, create a warm atmosphere, and be suitable for educational and health care buildings; at the same time, light colors have higher heat reflectivity, and the use of breeding sheds and storage roofs can reduce internal temperature and reduce energy consumption of cooling equipment.

Core performance advantages (addressing long-term usage pain points)
High-efficiency heat insulation and cooling: The light orange-yellow coating has high infrared reflectivity, and the roof surface temperature in summer is 8-12℃ lower than that of dark panels, which greatly reduces the energy consumption of building air conditioning and ventilation;
Salt-alkali environment resistance: Zinc-aluminum-magnesium substrate + anti-corrosion coating provides dual protection against ammonia in aquaculture sheds, soil moisture in saline-alkali land, and light salt spray along the coast. The anti-corrosion life can reach more than 10 years
Anti-bump and wear-resistant: The coating hardness reaches HB level, and scratches are not easily caused during the handling and installation of the plates. It can be used later to resist external force bumps and is suitable for park buildings with frequent personnel activities.

Purchase decision advice (precise selection reference)
Priority is given to purchasing for education, health care, and agricultural projects. Roofing in high-temperature areas in the south offers the highest cost-effectiveness. If used on the exterior walls of street-facing shops, a high-gloss orange and yellow version can be selected to enhance commercial recognition. In low-temperature areas in the north, no additional coating upgrades are required. Conventional modified polyester can meet weather resistance requirements, with a recommended thickness of 0.4-0.8mm, taking into account both cost and structural strength.

Common usage questions and answers
Q: Are orange-yellow color steel plates resistant to ammonia corrosion in aquaculture sheds?
A: The zinc-aluminum-magnesium substrate can resist ammonia and moisture erosion. With a special anti-corrosion coating, it is more suitable for the breeding shed environment than ordinary galvanized colored boards. It is recommended to clean the surface every 3 years to further extend the life.
Q: Will the matte version show dirt easily?
A: Low-saturation orange-yellow is a light, stain-resistant color with minimal dust adhesion. It can remain clean after rainwater cleans itself and is more suitable for long-term use in the open air than pure white or bright yellow.
