GENERAL INFORMATION
610/762 Corrugated Profile. Both are sinusoidal profile sheets and can be used as roofing and cladding material. With its origins dating back to the Victorian era, it’s probably the most commonly known sheeting profile used in the world today.
- There are two sizes of corrugated sheeting on the market, 8½ Corrugated and 10½ Corrugated. The numbers 8½ and 10½ refer to the number of corrugations across the width of the profiled sheet.
- The two types of corrugated sheeting have different cover widths. 610 has a cover width of 610mm and 762 has a cover width of 762mm.
- The fact that the corrugated profiled sheeting has been around since before the turn of the century proves that this easy to use and effective method of roofing and wall cladding is here to stay.
- Corrugated 610/762 can be factory cranked to a curve and bullnosed to a wide range of radii (see Bullnosing).

LENGTHS & ROOF PITCH
Corrugated sheeting can be ordered in any length up to 18 metres with the proviso that lengths over 13,2 metres require special transport arrangements. Corrugated sheeting is not suitable for roof pitches below 15º. If roof slopes longer than 15 metres are not recommended.
TOLERANCES
Length, width and edge wave tolerance of ±5,0 mm is permissible.
PURLIN SPACINGS
Purlin Spacings are dependent on both downward loading and negative suction loading caused by wind. Your engineer should be consulted to calculate your load (kn/m²) for your particular application. A broad guideline for Purlin Spacings is shown in the table below.
GAUGE | MAXIMUM PURLIN | MAXIMUM GIRT | |||
Spacing for Roof Covering | Spacing for Vertical Covering | ||||
Double Span | Single Span | Cantilever | Cladding | Cantilever | |
mm | metre | metre | metre | metre | metre |
0,50 (Full Hard) | 1,2 | 0,9 | 0,30 | 1,3 | 0,85 |
0,60 | 1,2 | 0,9 | 0,30 | 1,5 | 0,85 |
0,80 | 1,5 | 1,2 | 0,45 | 1,8 | 1,00 |
Double Span refers to a length of corrugated sheet being continuously supported over 3 or more purlins.
MASS / METRE | LINEAR METRE / TON | |||||||
Thickness | 0,4 | 0,5 | 0,6 | 0,8 | 0,4 | 0,5 | 0,6 | 0,8 |
762 | 2,976 | 3,717 | 4,464 | 5,952 | 336 | 269 | 224 | 168 |
610 | 2,494 | 3,115 | 3,731 | 4,975 | 401 | 321 | 268 | 201 |
Covering width will change if double side lap is used as opposed to a single side lap. 762 covering width will reduce to 686mm and 610 covering width will reduce to 535mm.
