Fastening material for sheet metal profiles

Fastening material for sheet metal profiles B

  • Fastening material is supplied by Lichtgitter CZ for all types of gratings and for all commonly supplied and designed types of supporting-structure profiles.
  • For BZ profiles, the so-called “olive” is used as the top part of the fastening element, inserted into the eye of the profile.
  • All bolts and nuts are supplied in stainless steel, or—like the other parts of the fastening material—in hot-dip galvanized finish.
  • By bolting sheet metal profiles together (fastening materials No. 27 and 29), we achieve a more favorable load distribution and prevent the formation of a trench edge.
  • Each individual profile, or profiles bolted into elements wider than 300 mm, must be fastened to the steel structure at least at four points. For widths below 300 mm, two fastening elements are sufficient.
  • All fastening elements must be inspected periodically, depending on the conditions of use, and screw connections tightened if necessary.

No. 21 Standard fastening element

It is an element consisting of a bottom part, an M8x… countersunk-head screw ISO 2009 (DIN 965), an M8 square nut DIN 557 and, for the BZ profile, the so-called “olive”.
The fastening element is intended for profile types BR, BP, BP-Ü, BZ and BN-O.

No. 22, 23 Hook-type fastening element

No. 22 is intended for sheet metal profiles supported on beams without a bottom flange (L profile) and consists of a lower hook, an M8x… countersunk-head screw ISO 2009 (DIN 965) and, for the BZ profile, the so-called “olive”. The type of beam for which the element is to be used must be specified in the order.
The fastening element is intended for profile types BR, BP, BP-Ü, BZ and BN-O.
No. 23 is the same as fastening element No. 22, but for beams with a bottom flange (U profile).

No. 24 Fastening using a spacer profile

Prevents the formation of a trench edge at the profile joint and at the same time ensures a proper connection of the profile to the supporting structure. It consists of a spacer profile, an M8x… countersunk-head screw ISO 2009 (DIN 965), alternatively self-tapping countersunk-head screws ISO 7050 (DIN 7982), washer 9 DIN 126, nut M8 ISO 7042 (DIN 980).
The fastening element is intended for profile types BN-O and BN-G.

No. 24 Butt joint – new

Used for fastening to the structure at the contact point of two profiles, without the need to drill holes into the beam. It consists of two clamps, a threaded strip with three M8x… screws according to ISO 7050 (DIN 7982) and two olives (see element No. 32).
The fastening element is intended for profile types BR, BP, BP-Ü, BZ and BN-O.

No. 25 Fastening element with “S” clip

It is an element consisting of an “S”-shaped hook, an M8x… countersunk-head screw ISO 2009 (DIN 965) and, for the BZ profile, the so-called “olive”. It is suitable only for beams with a flange thickness up to 9 mm.
The fastening element is intended for profile types BR, BP, BP-Ü and BZ.

No. 26 Direct bolted fastening

Ensures a secure connection to the supporting structure; it consists of an M8x… countersunk-head screw ISO 2009 (DIN 965), washer 9 DIN 126, nut M8 ISO 7042 (DIN 980) and, for the BZ profile, the so-called “olive”.
The fastening element is intended for profile types BR, BP, BP-Ü, BZ and BN-O.

No. 27 Connecting insert

In the case of unbolted parts, it prevents the formation of a trench edge at large spans and helps distribute the load. It consists of a connecting element and self-tapping countersunk-head screws M5x20 DIN 7516D.
The fastening element is intended for profile types BR, BP, BP-Ü, BZ, BN-O and BN-G.

No. 27 Connecting clamp – new

Prevents different deflections of loaded and unloaded profiles so that a trench edge greater than 4 mm does not occur. It consists of a spring steel clamp.
The fastening element is intended for profile type BZ.

No. 29 Bolted connection

By bolting sheet metal profiles together, we achieve a more favorable load distribution and prevent the formation of a trench edge. It consists of an M8x20 screw ISO 4017 (DIN 933), washer 9 DIN 126 and nut M8 ISO 7042 (DIN 980).
The fastening element is intended for profile types BR, BP, BP-Ü, BZ, BN-O and BN-G

No. 30 Fastening using an angle bracket

Prevents the sheet metal profile from lifting. It consists of an angle bracket 30/30/3…50 mm long and two self-tapping screws M5x20 DIN 7516D.
The fastening element is intended for profile types BR, BP, BP-Ü, BZ, BN-O and BN-G.

No. 31 Connecting strap

It is suitable for connecting individual parts to each other and for limited load transfer. This requires bolts, washers, nuts and a strap with holes adapted to the profile.
The fastening element is intended for profile types BR, BP, BP-Ü, BZ, BN-O and BN-G.

No. 32 “Olive”

Top part of the fastening element for the BZ profile, made of grey cast iron without surface treatment or plastic.

No. 34 Clamping clip

Using an appropriate tightening torque, the profiles are pulled against the structure with the required force. Thanks to this, they can transfer certain horizontal forces. It consists of a curved clip, an M12 x … bolt ISO 4017 (DIN 933), washer 13 DIN 126 and a self-locking nut M12 ISO 7042 (DIN 980), alternatively steelwork bolts according to DIN 7990.
The fastening element is intended for profile types BR, BP, BP-Ü, BZ, BN-G and BN-O.
