40mm steel roof battens

Roof battens are the rails the roof sheets or tiles fix to. This 40 mm batten is rolled from TRUECORE G500/G550 high-tensile steel with a galvanised or alloy coating to AS1397, so it stays straight and will not rot, warp or attract termites. The knurled surface helps footing and grip, and the rolled safety edges are easier on the hands.

It suits metal roof sheets as well as concrete and terracotta tiles, and it comes in 6.0 m and 7.5 m lengths. To work out how many you need, read what roof battens are and how many a metal roof needs. Batten screws are in roofing screws.

Frequently Asked Questions with Roof Battens 

1. What is a roof batten and what does it do?

A roof batten is a long, straight rail that runs across the roof trusses or rafters. This one is a 40 mm steel roof batten, rolled from TRUECORE high-tensile steel rather than cut from timber. Its main jobs are:

• Create a base for fixing roof sheets or tiles.

• Create an air gap for ventilation under the roof.

• Support the roof and help keep it strong and stable.

2. What size roof batten do I need?

The right batten depends on the roof sheet or tile going on it and on how the roof is designed. This listing is one batten size in two lengths:

• 40 mm TRUECORE steel batten, sold in 6.0 m and 7.5 m lengths.

• Always check your roofing material specs (for metal roofing or roof tiles) and local building codes to confirm the right size for your project.

3. Are these timber or steel roof battens?

Steel. They are rolled from TRUECORE G500/G550 high-tensile steel with a galvanised or alloy coating, so there is no timber to treat.

4. How many battens will I need for my roof?

The number of battens depends on your roof size and the type of roofing material:

• For metal roofing: Batten spacing depends on the roof sheet profile, your wind region and the manufacturer’s span tables, so check the sheet manufacturer’s installation guide before you order.

• For roof tiles: They are spaced closer together to match the tile size.

• Tip: Measure your roof area or talk to a builder to calculate the exact number.
