In modern industrial workshops, more than 80% of the workshops are in the form of steel structure construction, so ventilation and daylighting have become one of the urgent problems to be solved in steel structure workshops. Roof smoke vent has good ventilation, lighting and smoke exhaust functions, and therefore become a type of ventilation equipment that is frequently used in steel-structured workshops. What are the smoke vent rooflight? Generally speaking, there are roughly the following:

1. Steel plate for steel beam and steel column: hot-rolled steel plate 5mm-30mm thick, material is Q235A/B; Q345A/B.

The steel plate is processed into H-shaped steel, which consists of a web and two flange plates; there are constant-section H-section steel and variable-section H-section steel; the steel column set on the mountain wall is called the wind-resistant column.

2. Steel plate for purlin: hot-rolled steel plate 2mm-3mm thick, material Q235A/B; Q345A/B

The steel plate is formed by a continuous forming machine for purlins. After forming, it is divided into C-shaped purlins (C-shaped steel) and Z-shaped purlins (Z-shaped steel).

3. Steel plate for gutter: hot-rolled steel plate 2mm-3mm thick, material Q235A/B; Q345A/B

Used for roof drainage: Shearing machine, bending machine are processed and formed for paint treatment; considering anti-corrosion performance, stainless steel steel plate or hot-dip galvanized steel plate is also selected as the material.
