The Adjustable plug - in modular shelf is mainly composed of vertical column, transverse brace, oblique brace, beam, fork and hanging Angle, layer plate, sole plate, fastening bolt, etc.
1. Vertical frame sheet is composed of vertical column, transverse brace, diagonal brace, and sole plate, etc. Shelf column is made of 80*60*1.8mm and 55*47*1.5mm cold-bent section steel, transverse brace and diagonal brace are made of 1.0mm rectangular steel tube, and sole plate is made of 2.0mm thick cold-rolled plate.
2. Beam: The beam rod body adopts 50*30*1.2mm cold bending clasp welding "P" section steel;Left and right fork hanging Angle adopts 2.0mm thick cold punching bending plate.
3. The laminate adopts 0.7mm high-quality cold-rolled steel plate.
4. The stairs are made of 3mm high-quality anti-skid pattern board, and the floor is made of G323/40/100FP high-strength steel grid board.
5. Fixing bolts adopt national standard GB5781 series.
二．Shelf performance Indicators: All shelf components are made of high-quality raw materials through cold rolling processing, and their strength indicators are as follows:
1. Strength index of cold-rolled profile (N/mm2), steel type tensile, compressive, bending, shear, end face pressure (grinding flat top tight), Q235 cold-rolled profile 205 120 310
2. Each layer shall be loaded more than 250kg.
3. The overall strength and stability are in line with the standards specified in <<Technical Specification for Cold-formed Thin-walled Steel Structures>> (GBJ18-87).
