1. Primary Framing

Main steel frame is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plate, and adopts rust removal and anti-rust process such as shot blasting, painting and galvanizing. Welding, bolts or rivets are usually used to connect each member or component. Xinguangzheng’s pre-engineered steel structure building is custom-designed to meet your exact requirements. The most common primary framing systems are shown below. Practically any frame geometry is possible. Consult Xinguangzheng for your specific requirements.

2. Secondary Framing (Bracing, Z and C section purlin)

Purlin, tie bar and bracing are secondary structural members used to support the wall and roof cladding. Secondary members as purlin, tie bar, column bracing and horizontal bracing connect the main frame and help in resisting part of the longitudinal loads that are applied on the building such as wind and earthquake loads. Steel purlin is available in high grade steel conforming to GB/T 2518-2008, Q235B/Q345B Grade or equivalent, available in 1.8 mm. 2.0 mm, 2.2 mm, 2.5 mm and 3.0 mm thickness. The purlin come with a galvanized sheet. Column bracing is a connecting member set between two adjacent columns to ensure the overall stability of the building structure, improve lateral stiffness and transfer longitudinal horizontal force. Column bracing will be round steel or angle steel according to the building need.

3.Roof and Wall Cladding System

Xinguangzheng offers a complete line of Roof and wall steel sheet, sandwich panel, and their related accessories, steel cover, trims, eave gutter, curved eave cover, wall flashing for a wide range of building applications. Variety of profiles, base metal, metal substrates and coatings for its sheet. The metal sheet are used as roof and wall panels, interior roof and partition panel, etc. Steel sheet, its base sheet is usually be galvanized sheet or aluminium zinc sheet with organic coating. It has the advantages of good corrosion resistance, bright color, beautiful appearance, convenient processing and forming, and has the original strength of the steel plate and low cost. The thickness of steel sheet usually be 0.3mm-0.7mm and used in different building and requirement. Sandwich panel is composite insulation panel made by two sides steel sheet and heat insulated core material through binder (or foam). The core can be EPS (polystyrene ), fiberglass wool, rock glass wool and PU (polyurethane), thickness 50mm, 60mm, 75mm, 100mm, 150mm, 200mm, etc.

Core material: 1) Polystyrene: made of expandable polystyrene (EPS) particles as raw material, shaped like chemical fertilizer particles, after heating preform, white pearl like larger particles, and then heated in the mold and formed with a micro closed cell structure of foam board, due to poor fire performance, mostly used for temporary buildings. (2) Polyurethane: high energy saving performance, excellent fire insulation performance of the material, by adding flame retardant to achieve the purpose of fire prevention, combustion will produce toxic gas, when used to do composite panel, polyurethane bulk density is generally in 40 kg. (3) Rock wool: basalt as the main raw material, after high temperature melting, made of inorganic fiber by high-speed centrifugal equipment, at the same time evenly add a certain proportion of adhesive baking into a large panel, according to the production needs to cut strip piece then made to sandwich panel, rock wool as non-combustion body, good fire performance. (4) Fiberglass wool: It is a kind of light weight, heat resistant, elastic, non-flammable insulation material, widely used in chemical industry, medicine, factories, construction, is an ideal heat insulation, fire-retardant, sound-absorbing material. Advantages of sandwich panel: 1)Light weight; 2)Heat insulation, good sealing performance; 3)Convenient construction, flexible and fast installation, construction period can be shortened by more than 40%; 4)Bright color, beautiful appearance, no need for surface decoration; 5)High strength, can be used as maintenance structure, load-bearing structure, bending and compression resistance.

4. Steel Decking Floor

The pressed steel plates supporting the floor concrete are called profiled plates, also called floor bearing board. The steel decking board are widely used in multi-storey buildings such as power plant, exhibition hall, steel structure workshop, cement warehouse, steel structure office, airport terminal, railway station, stadium, concert hall, grand theater, large supermarket, logistics center, Olympic venues and sports venues and other steel structure buildings. It can adapt to the main steel structure rapid construction requirements, can provide a firm platform in a short time, and can take flow repetitive construction operation, laid a number of floors decking board, and pouring concrete slab.
