MINI ORB PRODUCT GUIDE
INTRODUCTION
DURABILITY
Corrugated iron was first invented and patented in England in the early 1830s and was the first mass-produced cladding material of the modern building industry. By the early 1850s, it had arrived in New Zealand and was soon adopted for buildings as diverse as huts on the early gold fields, for agricultural buildings and for houses, commercial buildings and factories. Today this practical and versatile profile, is in as much evidence and demand as it has been throughout its history in New Zealand.
All material selections must be compatible with prevailing environmental conditions and adjacent materials. In particular, areas of ZINCALUME® or COLORSTEEL® exposed to salt spray but not rain washing will require regular programmed maintenance. In high risk unwashed areas, a non-ferrous substrate is recommended. (Refer to New Zealand Steel Specifiers and Builders Guide for steel-based products.)
While originally available only in restricted lengths, the advent of long-run technology in the mid-20th century made corrugated metal even more popular. The new process allowed faster and more economical production, greater consistency length-to-length and avoided the need for multiple end laps. Steel & Tube has applied these principles to the manufacture of Mini Orb, a profile just as visually pleasing and versatile as its bigger brother CUSTOM ORB® except it is produced on a smaller scale. Although originally adopted for use with interior design projects, Mini Orb is now finding increasing utility in exterior applications. The close sinusoidal curves that define Mini Orb’s form also provide its function – allowing it to withstand distributed and impact loads, and providing a weathertight side lap. Mini Orb is available in the full palette of colours from the COLORSTEEL® ENDURA® and MAXX® ranges. Manufactured to perform under New Zealand’s unique environmental conditions, Mini Orb adds form, function and style to buildings, both inside and out. Take a closer look at specifying long-run Mini Orb by Steel & Tube.
INSTALLATION Handling and installation of Mini Orb should be carried out by competent tradespeople with appropriate care being taken in visually prominent areas. Generally, design details for Mini Orb cladding can be based on scaled-down versions of published details for vertical and horizontal CUSTOM ORB cladding. For specific information and design details contact our Steel & Tube Technical Helpline on 0800 333 247. Mini Orb may be used as roofing on open structures that do not require compliance with NZBC Clause E2.
MATERIAL SELECTION With 36 Colours in COLORSTEEL ENDURA and 18 in COLORSTEEL MAXX, Mini Orb is available in a comprehensive colour palette. Also available in Metallic colours in ColorCote®, and unpainted ZINCALUME and Galvanised. Thickness: .40mm.
