Steel bookshelves have begun to slowly replace solid wood bookshelves because they are not only more secure in quality, but also more beautiful in appearance. They are now widely used in institutions, enterprises, schools, shopping malls, family, etc. Why is it becoming more and more popular? How is the steel bookshelf made? So let’s take a deeper look at the steel bookshelf and see where its advantages are.
First, the production process of steel bookshelf
1. Plate
The processes from cutting, shearing, bending, stamping, welding, spraying, assembling, packaging, etc. are all operated by high-precision production lines with a degree of mechanization of 70%. In the production process, the next process checks the previous process. The quality of the products is high, and the unqualified semi-finished products are prevented from flowing into the next process, so as to check every layer.
2. Surface treatment
Process: high temperature degreasing – cleaning (first time) – rust removal – (pickling) – cleaning (secondary) – phosphating treatment – cleaning – drying – spraying – heating up to 200 degree of curing.
test:
A. Surface spray adhesion test.
B. One kilogram of steel balls can be naturally dropped at a height of 50 cm for impact, and the surface will not fall off.
Second, the advantages of steel bookshelves
1. Sturdy and environmentally friendly
Compared with traditional wooden bookshelves, steel bookshelves have obvious advantages in fire resistance, firmness and environmental protection. Steel bookshelves are generally made of steel plates, and the surface is electro-galvanized, hot-dip galvanized, powder electrostatic spraying, or sprayed with epoxy resin after phosphating, so the high hardness and strong coloring degree of steel bookshelves are formed. It will not peel off the paint or cause the surface to dent due to ordinary impact.
