How much do you know about the general knowledge of steel gratings?

For the general knowledge of steel gratings, you can know how many steel grating products mainly include: well cover, tree pool cover, standard steel grating, plug steel grating, toothed steel grating, marine steel grating, composite steel Grid, steel grating ceiling, steel grating guardrail, stair steel grating, gutter cover, platform tread, ball joint railing, profiled steel grating. Mainly used as industrial platform, ladder pedal, handrail, channel floor, railway bridge sideway, high-altitude tower platform, drain cover, manhole cover, road barrier, three-dimensional parking lot, institutions, schools, factories, enterprises, sports fields, The fence of the garden villa can also be used as an exterior window for a residential building, a balcony railing, a guardrail for highways and railways, and the like. Our company has a modern management system, a large number of management talents, strict quality control, product quality assurance, and market-oriented, to develop a reasonable price. Relying on scientific management mode and advanced production line equipment, we always pursue the quality of our products, and serve our customers with excellent quality, reasonable price and reliable reputation. We enjoy a high reputation among our peers and customers.
There are three series of steel grating flat steels: 30mm, 40mm and 60mm. To reduce the loss and cost, please design the layout of the steel grating according to the following rules:
1. The standard original plate size is 995×6000LB, and the layout should be 995mm as the width. The question of the plate spoon should be 10ram gap, and the remaining one should make up the rest.
2. When the plate width is less than 995mm, the closest width should be selected according to the flat steel modulus. For example, 800mm × 1500LB should be changed to 785mm × 1500mmLB
3, steel grid length can be optional, 仉 *** select 100mm multiple multiple 4, size representation: 995mm (board width) × 1500mm (board length) 30 pieces
The walkway platform grille plate actually needs to be customized with various specifications of steel ladder products. It can be made into any size by using any type of steel grating to match the corresponding stairs, but from an economic point of view, we recommend using our recommendation as much as possible. The size of the stair step steel grating can be divided into T1, T2, T3, T4.
1. From an economic point of view, it is recommended to use the modulus width as much as possible (series 1 uses 125, 155, 185, 215, 245, 275, series 2 uses 125, 165, 205, 245, 275 mm, etc.) as a multiple of 100 mm (eg 500, 600, 700, 800, 900, 1000, 1200mm, etc.).
2, stair step tolerance: width W ± 3mm, length L-3mm. In addition, we can provide stair treads with different non-slip front guards, the size of which can be arbitrarily specified. In general, we recommend the use of front panels of the following sizes. Set the stair tread plate to the type and area of the required steel grate and provide the size and number of pieces. Where large-area steel gratings are required, a plan view must be provided and the cross-sectional dimensions, location of the supporting steel beams and the direction of the opening of the channel are indicated. The position and size of the steel grating that needs to be opened or moved frequently. Location and size of the ribs, front guards and profiled interfaces. Note: The type and number of mounting clips, in principle, requires at least four sets of mounting clips per steel panel. The type, number and size of the ladder pedal, as well as the surface treatment status and whether the sides are chamfered. Stair tread surface treatment status (hot dip galvanizing, dip lacquer or no treatment). The steel grating is priced in square meters, the ladder pedal is priced according to the price, the installation clamp is priced according to the sleeve, the ribs are priced according to the meter, and the gutter cover is priced according to the sleeve. The stair tread area is calculated by the gross area, which is calculated according to the outer dimensions, including openings and notches. Once you have identified the above, you will get an accurate quote.
