Application

SW-straps type SP are used for crosswise and lengthwise support of roofs and ribs in mine working areas.
They are suitable to be used with expansion, resin, cable and tubular friction anchors.

Technical specification

SP-220 ; SP-270 ; SP-320 W-straps have a similar design. They differ only in terms of steel sheet thickness and section width. There are deformations for added strength and appropriately spaced holes along the straps (round or oval as requested). It is possible to connect two or more mats cross wisely or length wisely.
In terms of a range of application and production method the mats can be divided into the following types:
- W – strap type SPs
- W – strap type SPo
- W – strap type SPp
An attachment unit can be used for suspending elements of mining equipment, e.g. cables, pipes, etc.
Its maximum load capacity is 2.5 kN.
