Currently, there is a wide variety of steel and wood fire-rated doors on the market, with significant price differences. Some unscrupulous businesses are selling substandard products as high-end items to maximize profits, deceiving customers who are unfamiliar with steel and wood fire-rated doors. This greatly disrupts the industry order.
Therefore, customers must pay attention to the following points before purchasing steel and wood fire-rated doors:
Trim materials: Currently, the trim materials on the market are mainly divided into three categories:
1. Wood-plastic composite trim: The wood-plastic composite base material is covered with a film (PVC) or painted paper. Due to the lamination process used on the surface, the veneer easily separates from the base material during use, leading to blistering of the surface layer and powdering of the wood-plastic composite base material;
2. Steel-plastic composite trim: The steel-plastic composite base material is covered with a film (PVC). Due to the lamination process used on the surface, the veneer easily separates from the base material during use, leading to blistering of the surface layer.
Door panel surface treatment process: Transfer printing and baking paint process: The steel plate undergoes phosphating liquid anti-corrosion treatment, the bottom surface of the steel plate is powder-coated and baked, and the wood grain is heated and transferred to the paint on the bottom surface of the steel plate, then baked again. The surface uses automotive-grade baking paint technology.
The steel plate thickness is the most indicative aspect of product quality. Due to the diversity of market prices, the steel plate thickness also varies. To achieve a flat, smooth, and stable product surface, the steel plate thickness should be 0.5mm or more. Only then can it achieve good impact resistance and anti-collision performance.
