Product Core Introduction
The bean green pre-coated colored steel plate focuses on ecological nature and adopts a low-saturation bean green color scheme. The aluminum-zinc coated substrate is equipped with an environmentally friendly water-based modified coating. It is formaldehyde-free and heavy metal-free, and meets the environmental protection standards for green buildings. The coating is coated with plant weather-resistant additives, the color is soft and non-glaring, and it is highly integrated with green plants, mountains, forests, and park green environments. The boards are lightweight and easy to install, suitable for the enclosure needs of green buildings and ecological parks, and can be made into various shapes such as flat plates, corrugated plates, and antique tiles.

Adapt to usage scenarios (solve the pain points of scenario matching)
The core is adapted to ecological industrial parks, supporting buildings of scenic spots, seedling greenhouses, municipal green enclosures, facades of rural revitalization homestays, and supporting buildings of forest parks. Bean green can weaken the industrial feel of steel structures, naturally connect with surrounding green plants, and create immersive ecological buildings; at the same time, it can adapt to the antique transformation of scenic spots and homestays, taking into account the durability of modern panels and natural visual effects.

Core performance advantages (addressing long-term usage pain points)
Environmentally friendly and zero-pollution: The water-based coating has passed EU RoHS testing, has no irritating odor, and will not release harmful substances when used indoors or outdoors in scenic spots and homestays, meeting green building evaluation standards;
Mold-resistant moss: The coating has a antibacterial formula. In scenic areas with high humidity and dense green plants, the board surface is less likely to grow moss and mold, avoiding black spots and coating rot problems;
Lightweight construction: Aluminized zinc substrates have lower density and are lighter than galvanized sheets at the same thickness, reducing building loads, making installation of scenic mountain projects more convenient, and shortening construction cycles.

Purchase decision advice (precise selection reference)
Ecological scenic spots, rural homestays, and green industrial parks are preferred, pursuing the preferred color system that integrates architecture and nature; for high humidity and multi-green environments, it is recommended to choose the aluminum-zinc coated substrate version, which has better anti-mold and moisture resistance effects; if used in seedling greenhouses, the light-transmitting auxiliary version can be customized to take into account both sunshade and lighting needs.

Common usage questions and answers
Q: Will green color steel plates grow moss in humid scenic areas?
A: The special antibacterial coating can inhibit the adhesion of moss and mold. Regular and simple rinsing can keep the board surface clean. It is more suitable for high humidity ecological environment than ordinary green board.
Q: Will the water-based coating have poor wear resistance?
A: The water-based coating is combined with a hardening aid, and the hardness meets the standard. Daily wind and rain scour and minor dings will not damage the coating. The durability is the same as that of oil-based polyester board, and the environmental protection is better.
