Steel and wooden door surface treatment technology and surface thickness

Nowadays, most homes use steel-wood doors. The quality of the steel-wood doors that enter the home, that is, the armored door, directly involves safety issues. There are many brands of steel-wood doors on the market. Different brands and different styles of steel-wood doors have different surface treatment processes. In order to better and more expertly choose steel-wood doors, it is necessary for users to understand the surface treatment process of steel-wood doors and the surface thickness of steel-wood doors. Understand With this knowledge, you will have a good idea when choosing steel-wood doors.

Steel and wooden door surface treatment technology

The surface treatment technology of steel and wooden doors on the current market is mainly divided into two categories:

1. Film sticking process: steel plate surface The production process of PVC material with imitation wood grain (i.e. composite plastic) is that the PVC material is heat-sealed and pasted on the steel plate. During use of this type of product, degumming, delamination, leg discoloration, etc. may occur due to changes in cold and heat. Phenomenon, and the degumming and rusting phenomenon are more serious after scratching the surface with sharp objects.

2. Transfer paint process: The steel plate is treated with phosphating solution for anti-corrosion → the bottom surface of the steel plate is sprayed → baked → the wood grain is heated and transferred to the paint on the bottom surface of the steel plate → baked → the surface is painted with automotive paint The technology and performance are relatively stable.

Surface thickness of steel-wood doors

The thickness of steel plates best reflects the quality of steel-wood doors. Due to the diversification of market prices, the thickness of steel plates also varies. The difference is that if the product surface is to be smooth, smooth and stable in performance, the thickness of the steel plate should be 0.5mm or above, so that its anti-collision and impact resistance can achieve good results.

Some steel and wooden door companies use inferior products that use 0.3mm or thinner steel plates, resulting in poor surface flatness and insufficient door body rigidity. Such products have seriously disrupted the normal competition in the steel and wooden door industry.order, harming the interests of consumers, and bringing more quality complaints and after-sales problems to dealers of steel and wooden doors. It is recommended that the market resolutely boycott such inferior products.
