Steel roof truss
- Commodity name： Steel roof truss
- Product Description
-
Steel roof truss products mainly include several types such as portal frame structure, pipe truss structure, frame structure, and angle steel roof truss. Each type has its own characteristics and applicable scenarios:
● Portal frame structure: Long service life, low maintenance cost, beautiful appearance, suitable for various process requirements, with less on-site welding, mostly using bolt connections, conducive to construction quality control and material recycling, especially suitable for factory construction.
● Pipe truss structure: Suitable for buildings with extra large spans, such as sports venues, swimming pools, etc., but with long construction periods, large on-site welding quantities, and high processing costs, it is generally not recommended for buildings with spans below 30 meters.
● Framework structure: mainly used for multi story buildings and industrial and civil buildings with complex usage functions, such as furniture plazas, supermarkets, warehouses, etc. with more than two floors, which can meet complex usage needs.
● Angle steel roof truss: Due to the development of steel structure technology, angle steel roof trusses are gradually being replaced by portal structures. Due to their high steel consumption, small utilization space, and easy deformation, they pose safety hazards and are now basically not used.
Steel skeleton lightweight roof panel
Steel skeleton lightweight roof panel is a common steel roof truss product, which has the following characteristics and advantages:
● Construction: The main ribs are made of cold-formed thin-walled C-shaped steel, the end ribs are made of cold-formed thin-walled C-shaped steel, the roof panel reinforcement is made of cold drawn low-carbon steel wire mesh, and the panel surface is made of lightweight composite core material and composite anti-seepage layer.
● Advantages: It has the characteristics of thermal insulation, fire prevention, corrosion prevention, lightweight, flexible design, and convenient construction. The fire resistance performance reaches A1 level, and the fire resistance limit can reach two hours; Strong corrosion resistance; Low heat transfer coefficient and good insulation effect.
● Application scope: Widely used in large-span industrial plants, warehouses, sports venues, gas stations and other places, suitable for sloping or grid structure roofs with steel structures as the main body.
Application fields and market demand of steel roof truss products
Steel roof truss products are widely used in multiple fields:
● Industrial buildings: such as automobile manufacturing factories, electronic equipment production plants, etc., require large spans to meet the layout of production equipment and material handling.
● Commercial buildings: such as commercial complexes, shopping centers, hotels, etc., can be designed with large-span, column free commercial spaces.
● Sports venues: meet the requirements of large space and high seating capacity for spectators, with short construction period and light weight.
● Public buildings: densely populated buildings such as auditoriums, transportation stations, hospital lobbies, and exhibition halls.
● Energy sector: supporting structures for wind power towers and petrochemical facilities.
