LYSAGHT CUSTOM ORB®

Product Description and Features

LYSAGHT CUSTOM ORB® is the famous BlueScope Lysaght Australian corrugated profile, equally at home with traditional and contemporary design. It is long, wide, strong, lightweight and economical. It can be aligned quickly and easily. Add up these features and you have a steel roof or wall cladding that simply offers outstanding value.

  • Can be used for both roofing and walling applications
  • Available in standard COLORBOND® steel and COLORBOND® Metallic steel colours and ZINCALUME® steel (for extreme conditions COLORBOND® Ultra steel may be made available)
  • Roof sheet lengths of up to 24m can be used before an expansion joint is required

Common Uses of this product

Roofing and walling in industrial, commercial, and residential applications, internal and external feature walls, heritage renovations.

Warnings

  • LYSAGHT CUSTOM ORB® is not suitable for machine curving - for bullnosing use LYSAGHT CUSTOM BLUE ORB®
  • Minimum recommended roof pitch is 5 degrees (1 in 12)
  • Lead and copper are not compatible with ZINCALUME® steel or COLORBOND® steel
  • Ensure selection of suitable material for environmental conditions for maximum durability
  • Read full details on Guidelines for using COLORBOND® steel & ZINCALUME® steel.

Specification

LYSAGHT CUSTOM ORB® is made from:

  • ZINCALUME® steel complying with AS1397-2001 G550, AZ150 (550MPa minimum yield stress, 150g/m2 minimum coating mass).
  • Stainless steel standard grade designation is AISI/ASTM Type 430; UNS No. S43000.

The base metal thickness is 0.42 or 0.48mm.

The COLORBOND® steel complies with AS/NZS 2728: 1997.

Lengths

Sheets are supplied custom cut.

Colour Range

LYSAGHT® products are normally available in the standard range of COLORBOND® steel colours. View the standard colour range for:

Maximum Support Spacings

The maximum recommended support spacings are based on testing in accordance with AS1562.1-1992, AS4040.1-1992 and AS4040.2-1992.

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 serviceability and strength limit states for particular projects.

Limit States Wind Pressures

The wind pressure capacities are based on full scale tests carried out at BlueScope Lysaght's NATA Registered Testing Laboratory using the 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 AS4040.2-1992, Resistance to Wind Pressures for non-cyclone Regions. **

The pressure capacities for serviceability are based on a deflection limit of (span/120) + (maximum fastener pitch/30).

The pressure capacities for strength have been determined by testing the cladding to failure (ultimate capacity). These pressures are applicable to the cladding being fixed to a minimum of 1.0 mm, G550 steel.
