Metal Steel Structure Frame
Product Description:
| List of warehouse materials: |
| The basic components of light steel structure | 1. Main rigid frame: composed of columns and beams;If there is a crane, a crane girder
is also included.
A.common materials: Q235, Q355;
B. Common cross-sectional forms of beams and columns: H-shaped
steel, trusses (beams are mostly used), lattice columns;
C. Common structural forms: portal rigid frame, frame structure; |
2. Support system: including tie rods, horizontal supports, inter-column supports, and
corner supports.
A. Tie rods are usually used: steel pipes, rectangular
pipes;H-beam, channel steel, C-beam, angle iron and so on can also
be used;
B. The inter-column support is usually used: round steel, steel
pipe, angle iron;H-beam, channel steel, I-beam, etc. can also be
used;
C. Angle braces are usually used: angle iron; |
3. Enclosure system: including purlins, purlins rods, roof panels, wall panels, doors,
windows, lighting panels, and gas floors.
A. Purlin: mainly used, C-shaped steel and Z-shaped steel are
cold-formed with hot-drawn steel plate and hot-rolled galvanized
steel plate.
B. Wall and roof color plates: mainly using high-strength,
cold-rolled color steel plates, galvanized or aluminum-zinc color
steel plates, stainless steel plates, aluminum alloy plates, and
titanium alloy plates.Commonly used in China is galvanized or
aluminum-zinc color steel plate. |
| Material classification | 1. According to the composition of the material: ordinary carbon steel (Q235) and ordinary low-alloy steel (Q355,
Q390, Q420);Ordinary low-alloy steel is the addition of one or
several alloying elements on the basis of ordinary carbon steel.
2. According to the intensity: Q235, Q355, Q390, Q420;Among them, Q235 and Q355 are commonly used
materials. |
