Sag bars
Connected between the purlins to avoid the purlin twisting mid bay. Also hold the button flange in place under uplift conditions.
Rolled from galvanised steel to the exact measurement required to ensure an accurate application.
Apex Ties
A small section designed to hold the top two roof purlins in line and tie up both sides of the slope together.
Diagonal Wire Ties
Used in horizontal application (side rails), in conjunction with side rail, supports to hold the sections level.
There are 3 basic applications of Diagonal wires ties
Mid Bay Support System
Split Bay Support System
Part Bay Support System
Bolted to the cleats on the column then together under the side rail support at the centre bay.
Generally used on bays ranging in size from 4.5M to 6M
Spilt Bay Support System
Used on bays over 6.1M to 9M
Two side rail supports to add additional strength and support side rails.
Wire Ties fixed to cleats on the column, and to the underside of side rail support.
Part Bay Support System
Similar to the Mid Bay Support System, but in this case only half of the bay needs to be supported as there is a door post to the side.
Side Rail Supports
Galvanised support bars designed to add stability to side rails.
They are used in conjunction with diagonal wire ties to ensure that the rails remain level while adding stability against wind pressure or suction loads.
All holes in the cleat of section are designed to connect the side rail holes.
Eaves Beam to side rail supports.
Galvanised support bar joining the underside of the Eaves beam to the side rails. Bolted the same way at the side rail supports.
Eaves Ties
Galvanised bafe tying the eaves beam to the first Z Purlin up the slope.
The cleat connected to the eaves beam is at an angle (due to the pitch of the roof) so it will pick up the z-purlin up the slope.
Bolted to the face of both the eaves beam and the Purlin it holds the sections level and strong.
