Gratings and stairs

Gratings and stairs

Gratings and stairs are made from various types of gratings. They are constructed with special side plates, measuring 70x3mm, and with L anti-slip profile.

The gratings are bolted on the steel carriers of the stairs with galvanized bolts M12x30.

Galvanized gratings

There are several types of galvanized gratings:

  • Drains and channels
  • Transient gratings
  • Pressed – welded grating
  • Pressed grating

 

Drains and channels

Drains or channels consist of a frame made of L profile with connecting bars and anchors.

Based on their practical application, for this purpose are used different types of gratings.
Drains are suitable for driveways, roads, bridges, car parks and pedestrian areas.

In comparison with cast iron gratings, these hot-dip galvanized gratings are much better.

They are flat on the surface, have a large surface for drainage (63-79%), flexibility in vibrations, low weight and the possibility for theft protection.

Grating’s load submission is in accordance with DIN 1072 standard.

Forge-welded gratings

Forge-welded grating type C is made of a material type S235JR, to EN 10025 standards with bearing grid and transverse wire. It is hot-dip galvanized according to EN ISO 1461standard.

The bearing bar comes with or without notches, with height ranges from 30 to 80mm. Cross-section of bearing bar ranges from 3 to 5mm. Mesh dimensions are 33x76mm.

For bigger loads, a heavy-duty version is used with mesh dimensions of 43x83mm, and a bar cross- section of 8mm.

 

Pressed-welded grating

Pressed-welded grating (type A) is transversely welded to squarely twisted or round bar, according to DIN 24537 standard, and hot-dip galvanized according to EN ISO 1461Europian standard. It is made of a material type S235JR, according to EN 10025 standard. The bearing bar comes with or without notches, with height ranging from 25 to 50mm.  Mesh dimensions are 34x38mm. Cross-sections of bearing bars are 2-3 and 5mm. Standard dimensions of grating panels are 6100x 1000 mm.

Pressed-welded grid type A is used:

  • as a tread for covering of channels and drains;
  • as tread on platform of various structures.

 

Pressure Locked Gratings

Pressure Locked Gratings (type B) is made of a material type S235JR, in accordance with EN 10025 European standard, pressure locked according to DIN 24537 standard, and hot-dip galvanized according to EN ISO 1461 standard.

The bearing bar comes with or without notches, with height ranges from 25 to 40mm. Cross-section of bearing bar ranges from 2 to 3mm. The height of the transverse bar is 10mm, and its cross-section is 2mm. The options for mesh dimensions are 33x33mm or 33x11mm.
