Methods of fastening the grating

One of the significant advantages of gratings is the ease of fastening the gratings. With the help of standard fasteners manufactured by our plant steel grating can be attached to almost any element of supporting frame - I-beam, channel bar, angle bar and shaped pipe. The gratings are attached without the use of welding, which allows maintaining corrosion protection. Only the simplest tools (ordinary wrenches), which are available at every construction site, are needed for installation. To calculate the number of fasteners the standard rule is used: 4 pcs. per 1 m2, but not less than 4 pcs. per one grating. That is, if the gratings are of a small size (for example, 700x652 mm), 4 fasteners are needed for reliable attachment of such a grating. If it is necessary to use several types of fasteners for the same structure, installation diagrams indicate which fasteners need to be mounted in the specified places. All types of fasteners are as invisible as possible and provide comfortable and safe movement on the flooring for both pedestrians and wheeled vehicles.

When developing installation diagrams for laying gratings, our specialists select the types of fasteners required in each case and draw up an appropriate specification, which is an integral part of installation diagram. Also, installation locations of the fasteners can be marked on the drawing at the request of the customer. Thus, when ordering the grating, the client can be sure that the supplied gratings with fasteners will be 100% consistent with the technical specification.


Types of fasteners

Standard fasteners are the most versatile type of fasteners and are used to mount gratings on elements with T-bar, I-beam, channel bar and angle bar.


Bracket with self-tapping screw this type of grating attachment is recommended to prevent self-unscrewing if the grating is subject to constant vibration loads. The delivery set includes a bracket with a reduced hole diameter (7 mm) and a self-tapping screw in accordance with the customer expectations. The disadvantage of this type of fastening is the need to replace the screws after each removal of the grating.

Hook attachments - such attachments are used in cases where there are no shelves on supporting structure for pressing the grating, for example: shaped pipe, channel bar pointing towards the grating, at least 4 pcs. per one grating. That is, if the gratings are of a small size (for example, 700x652 mm), 4 fasteners are needed for reliable attachment of such a grating.

If it is necessary to use several types of fasteners for the same structure, installation diagrams indicate which fasteners need to be mounted in the specified places.

All types of fasteners are as invisible as possible and provide comfortable and safe movement on the flooring for both pedestrians and wheeled vehicles.

Clamp for connecting gratings – it is a special type of fastener for connecting adjacent gratings. This type of fastening does not connect the grating to supporting frame, but only connects the adjacent gratings and thus transforms the individual gratings into a continuous grating. This makes it impossible for the gratings to slide off the frame, and also levels possible height differences between adjacent gratings in cases where one of them is under heavy load and the other one is not. This can specifically happen when moving the transport trolley over the grating.

Fastening for stair treads

Fastening of stair treads is carried out using ordinary bolts with nuts and washers. Hot-dip galvanized M8x35 bolts are supplied as default option
