The lattice is drainage

Lattice for trays drainage, a mat l — otsinok. steel, welding of 1000 of mm, century of 3 mm, highway of 136 mm Cellular execution.

Cellular lattice from galvanized steel. Length is 1000 mm, height is 30 mm, width is 136 mm, the crack size 30kh10mm, weight is 3,5 kg, a class — B. Will depend on the choice of a suitable lattice, not only a qualitative drainage system, but also your safety. Therefore at the choice of a lattice, it will be necessary to be defined for a start what to occur loadings and with what frequency (for example at the movement of the car weighing up to 1,5 tons and the movement 2 times a day can be established a steel stamped lattice, with a bigger weight of the car from 1,5t to 2,5t it is possible to establish a steel welded lattice, for loading to 15 t it is desirable to use a lattice from high - strength cast iron), then to consider whether there will be a movement of pedestrians (in avoidance of hit of female hairpins in cells of lattices, in avoidance of it the steel welded lattice will approach), it is also necessary to pay attention to an installation site of channels if channels are put on the street, then it is desirable to use galvanized lattices in order that in 2 - 3 years it was not necessary to tint them.
