A-type Grating

Weland A-Type Grating looks the same way today it did when we started to produce gratings fifty years ago.

The method of manufacturing, though, has been altered, and today Weland A-type grating is manufactured automatically by machines of high precision and capacity.

Weland A-type grating is kept in stock with mesh sizes and formats for purposes generally asked for.

Besides Weland A-type grating kept in stock gratings are manufactured in sizes and mesh sizes as required by the customer. As standard this type of grating is supplied hot dip galvanized, but can also be manufactured from stainless steel and aluminum.

A-Type Grating Dimensions / Load Capacity

The distance between the load bearing bars and their dimensions determine the load capacity of the grating. The height of the load bearing bars lie between 20 and 60 mm as standard and are adapted to the load expected.

Contact Weland for assistance and advice on dimensioning!

Surface Treatment

Weland A-type grating is hot dip galvanized as standard in accordance with Fe / Zn SS-EN ISO 1461.

Other types of surface treatment can be offered, for example painting of different kinds, anodizing etc.

A-Type Grating Mesh Size

Weland A-type grating is manufactured with mesh size 22 x 22 mm and 33 x 11 mm as standard. Other mesh sizes can be manufactured upon request, but, of course, with given limitations.

Distance between load bearing bars:
This measure is principally optional, but must not exceed 100 mm.

Distance between cross bars:
This measure is limited to multiples of 11.1 mm, thus 11.1 - 22.2 – 33.3 – 44.4 etc.
