* Upon customer’s request gratings of other dimensions and forms - rectangular, triangular, round, trapezoid, etc., can be supplied.

Gratings are fastened with self-tapping bolts and saddles.

Recommendations for ordering gratings

While choosing grating geometrical dimensions its maximum parameters 1500x1000 mm should be taken into consideration. The first dimension is bearing strip maximum length, and the second one is binding strip maximum length. A binding strip fixes bearing strips and bears no load. If a grating is properly orientated the bearing strip is perpendicular to motion and have its ends resting on bearing elements (angles, beams, channels, etc).

Grid treads

The company fabricates grid treads with or without protective hot-dip galvanization to GOST 9.307-89 or ASTM A123. All treads have antiskid edges (nonslip noses). For regions with specific climatic conditions and places with high slipping danger (due to snow, rain, ice or oil) treads are provided with antiskid cutouts.
