Steel Structure Building Solution

Let our client buy the most cost-effective steel structure!

YILI Steel Structure factory building structure is mainly composed of horizontal structure and vertical structure. Horizontal structure system is bent (including roof truss, beam and column) as the basic bearing structure, to bear the roof under load, horizontal wind load, earthquake action, the vertical load and horizontal level of crane load. Between the longitudinal structure system is made up of column, column support beams, walls, etc. In addition, there are houses, walls and roof support, to form a space rigid frame.

A complete steel structure warehouses and factories is composed of several different functional systems, mainly including: structure system(including main structure, roof and purlin system, wall and beam system),maintenance system ( including roof panel, wall panel, covering and floor deck), door and window system(including door and window), ventilating system (including clerestory system and ventilators), drainage system (including gutter, rain-spout and awning),etc

1.Structure System

(1)Main materials: Chinese national standard steel Q235 and Q345; Shaping method can be divided into Hot Rolled Steel and Welding Steel; Anti-rust of Painting and Galvanization are two main ways for the anti-rust treatment of steel structure. For large steel fittings we recommend to use paintings, while small fittings and cold formed steel are recommended to galvanize.

Also fire-proof coating should be painted on the steel structure according to local requirements.

H section: column and rafter
Material:Q235/Q345
Surface: Galvanized zinc coat or two-layer of rich-zinc epoxy paint
Usage: Make up the main steel structure frame

C/Z purlin C80~250mm, thickness 1.8~3.0mm
Material:Q235 or Q345 Surface: Galvanized zinc coat
Classification: Z purlin and C purlin
Applications: For supporting protection structure panels

(2)Roof purlins and wall beams: Use cold formed steel, the structure form can be divided into C shape simple beam mode and Z shape consecutive beam mode.

a. Use rigid support with section size L40*2, and set round steel braces on the eaves and ridge. 

b. Connecting materials are:

2.Maintenance System

The maintenance system for steel structure ware house mainly use colored steel sheets or sandwich panels. For the pressed steel floor deck system, we use glass wool as the heat insulating material. For lighting, PVC lighting boards are needed.

Roof sheet and ridge tile
Color: Ral. colors, optional Thickness:0.2-0.8mm
Usage: Roof or wall panels for steel structure buildings panels
We have several lines of process, can produce many types of corrugated sheets

Sandwich panel/cladding panel
Made up by two PPGI surface sheets and core material
Classification as shapes: Wall panel and roof panel
Wall panel: one side is PPGI corrugated sheet, another side is plain PPGI sheet or both sides are small wave sheets.
Roof panel: top side are PPGI corrugated sheets, another side is plain or small wave sheets.
Classification as core materials: EPS sandwich panel, Rockwool sandwich panel, PU/PIR sandwich panel etc
Applications: Fire protection and warm insulation
Advantage: Removable, light weight and easy to installe

3.Door and Window System

(1)Door: normally we have side hang door, sliding door and rolling shutter.

(2) Window: important lighting and ventilating components for warehouses or factories. normally we have: Aluminum alloy window, Plastic steel window, Sliding window, Side hung window, Awning window, Fixed door, Fenestration, single/double Glass window, Blinds, electric and manual window, etc.

4.Ventilating System

For warehouses and factories with large construction area and risk of fire, mechanical ventilators or natural ventilators in the middle of the construction are needed because it’s too deep to extract smokes through the openings of the wall. Normally we have:

(1)Clerestory: its main functions include ventilation, lighting, smoke extraction.

(2)Non-powered turbine ventilator: to achieve the effect of ventilation and smoke extraction by wind. It’s light and easy to install. Stainless material makes it durable. With special bracing structure, it can survive typhoon. It is widely applied and it doesn’t leak.

5.Drainage System

(1)Drainage system can be divided into non-organized drainage and organized drainage. non-organized drainage refers that the rain on the roof falls on the outdoor ground through eaves, and there is no need to set gutter and downspout. organized drainage refers that rain on the roof falls on the gutter and flows to the downspout.

(2)Components of organized drainage system Gutter: can be divided into steel sheet gutter, steel board gutter and stainless gutter according to its material. Downspout: PVC downspout and steel board downspout are commonly used.

(3)Awning: Steel awning: simple shape
