Roof steel sheet application

Roof steel sheet application

1. Wholesale GL steel sheet has sound insulation, good thermal insulation performance - porous foam core layer has good sound insulation and thermal insulation properties
2. Large area, light weight - light body materials, reduce building load
3. Rich in color, long-lasting stability - fluorocarbon paint coating, rich in color, smooth surface, acid and alkali resistance, mildew, rain as new
4. High toughness and high strength - better toughness and strength than similar products
5. Convenient construction--The product can be directly nailed, drilled, sawed, planed, and easily handles special roof shapes such as façades and arc windows.
6. Good fire performance - material resistance to burning grade B1, is a flame retardant material

Geomembrane construction method

Geomembrane construction method

The hot sale hdpe geomembrane pond liner should not be stretched too tightly. The soil embedded in the soil at both ends is corrugated. Finally, a 10cm layer of transition layer is laid on the HDPE geomembrane on the paved HDPE geomembrane and 20-30cm. Stone (or enamel prefabricated block) is used as an anti-shock protection layer.

During construction, efforts should be made to avoid the stone directly on the geomembrane. It is best to carry out the construction of the protective layer while laying the film. The joint of the composite geomembrane and the surrounding structure should be anchored by expansion bolts and steel strips, and the joints should be painted. Emulsified asphalt (thickness 2mm) is bonded to prevent leakage of bentonite waterproof blanket at this place.

Geomembrane Technology

Geomembrane Technology

Geomembrane anti-seepage film technical requirements are as follows

1. Before the laying of dam liner/fishing farm/shrimp liner Hdpe geomembrane, the corresponding certificate of conformity acceptance should be obtained from the civil engineering project.

2. Before the HDPE geomembrane is cut, the relevant dimensions should be accurately measured, and then cut according to the actual size. Generally, it should not be cut according to the size of the figure. It should be numbered one by one and recorded in a special form.

3. When laying HDPE geomembrane, the weld seam should be the least, and under the premise of ensuring the quality, the raw materials should be saved as much as possible, and the quality can be easily ensured.

4. The geotextile lap width of the joint between the film and the film is generally not less than 10 cm, and the weld alignment direction is usually parallel to the maximum slope, that is, arranged along the slope direction.

Preparation before lifting the roof panel

Preparation before lifting the roof panel

The components such as T-Type corrugated gl roofing sheet for sale produced in the prefabrication plant shall be transported to the site by means of transportation means. The choice of transportation mode shall be based on the size and weight of the components, the number of components and the distance of transportation, and the specific conditions of the existing transportation vehicles. Determine after comparison. It is generally transported by car and flatbed trailers, and the components are transported directly to the construction site.
During transportation, the components must be protected from deformation, non-dumping, and damage; the transportation road should be flat and solid, and the speed should be determined according to the road surface conditions to maintain a smooth running; the concrete strength of the reinforced concrete members should not be less than 70% of the design strength level; The loading and unloading of the components should be stable, and the transportation should be fixed firmly to avoid dumping; the position of the component pads should be correct during transportation, and the loading and unloading points should meet the design requirements. Transportation work should be reasonably organized, and should be hoisted first and supplied according to the hoisting order.
After the components enter the site, they should be stacked according to the plan layout plan of the structure hoisting plan prepared in advance to avoid secondary transportation. Generally, large-scale components such as columns and roof trusses should be placed in accordance with the layout plan of the components in the construction organization. The small and medium-sized components are stacked at the specified positions. Generally, the beams can be stacked 2-3 layers and the roof panels can be 6-8 layers.
