Specification
- ZINCALUME® steel complying with AS 1397-2001 G550, AZ150 (550 MPa minimum yield stress, 150 g/m2 minimum coating mass)
or - Stainless steel standard grade designation is AISI/ASTM Type 430; UNS No. S43000
The COLORBOND® steel complies with AS/NZS 2728: 1997.
Cladding and Style Capping Strip
G550, AZ150 (550 MPa minimum yield stress, 150 g/m2 minimum coating mass). The base metal thickness is 0.42 or 0.48mm.
Style Capping Strips
If you want the look of concealed-fixing, where the heads of the screws are hidden, you can fit optional Style capping strips. These strips are clipped to cap-type sealing plates instead of standard sealing plates.
Style capping strips can be manufactured in a colour that matches or contrasts with your LYSAGHT INTEGRITY® 820 roof.
Sealing Plates
G300, AZ150. The base metal thickness is 1.0mm.
Tolerances
Length: +0mm, -15mm
Width: +10mm, - 0mm
Lengths
Sheets are supplied custom cut.

Spanning Tables
The maximum recommended roof support spacings are based on testing in accordance with AS 1562.1-1992, AS 4040.0-1992 and AS 4040.1-1992.
Roof spans consider both resistance to wind pressure and light roof traffic (traffic arising from incidental maintenance).
Wall spans consider resistance to wind pressure only.
The pressure considered is based on buildings up to 10m high in Region B, Terrain Category 3, Ms=0.85, Mi=1.0, Mt=1.0 with the following assumptions made:
Roofs:
Cpi=+0.20, Cpe=-0.90, Kl=2.0 for single and end spans, kl=1.5 for internal spans.
Walls:
Cpi=+0.20, Cpe=-0.65, Kl=2.0 for single and end spans, kl=1.5 for internal spans.
These spacings may vary by the serviceability and strength limit states for particular projects.

Capacity & Load Tables
INTEGRITY® 820 offers the full benefits of the latest methods for modelling wind pressures. The Wind pressure capacities tables is determined by full scale tests conducted at BlueScope Lysaght's NATA registered testing laboratory, using direct pressure-testing rig.
Testing was conducted in accordance with AS 1562.1-1992, Design and installation of sheet roof and wall cladding-Metal, and AS 4040.2-1992, Resistance to wind pressures for non-cyclonic regions.**
The pressure capacities for serviceability are based on a deflection limit of (span/120) + (maximum fastener pitch/30).
The pressure capacities for the strength have been determined by testing the cladding to failure (ultimate capacity). These pressures are applicable when the cladding is fixed to a minimum of 1.0mm, G550 steel supports.
For material less than 1.0mm thick, please Contact Us.
