The channel is intended for use in reinforced concrete with a minimum compressive strength class of C20/25 or greater.

The 31/21 Axis Curve is a medium duty cast in channel that provides a load capacity exceeding that of a standard 38/17 channel section. The channel is intended for use in reinforced concrete with a minimum compressive strength class of C20/25 or greater. The channel assembly consists of the channel section, combined with welded studs, and a specially designed T Head Bolt.

The channel is designed to be used exclusively with ACS systems, with its main use being to fix back ACS Masonry Support brackets.

Axis Curve is produced from Stainless Steel, 1.4301 (304) grade and is supplied with welded anchor studs at 150 mm centres.

The 31/21 Curve has been tested to attain design resistances for easy comparison to applied design loads. The resistances are dependent on distances to the edge of the concrete.

ACS Curve T Head Bolts:

The ACS Curve T Head Bolt is designed, manufactured and tested in line with the guidance of BS EN ISO 3506-1:2009, Mechanical Properties of Stainless Steel Fasteners The Bolt is installed into the slot between the lips of the channel and rotated through 90°. During this operation, the bolt engages with the curved profile of the channel and is driven forward in the channel until the bolt locks into the front of the channel allowing ancillary components to be fixed. The bolt has a slot feature on the end of the shank to illustrate its orientation, which should be approximately vertical in its final fixed position.
