Step 1: Choose Your Barrier Rail

Select the type of Armco barrier rail:

1.6m Armco Barrier Galv/Yellow – ideal for flexible layouts and tighter spaces
3.2m Armco Barrier Galv/Yellow – fewer joins, faster installation for longer runs

The calculator will automatically determine how many rails are required based on your selection.

Step 3: Select Your Post Type

Choose how your barrier will be supported:

Dig In RSJ Posts – maximum strength for high-impact areas
Dig In Z Posts – cost-effective for lower-impact environments
Bolt Down RSJ Posts – heavy-duty surface-mounted option
Bolt Down Z Posts – lightweight and easier to install

Step 4: Add Fixings

Fixings are required to securely assemble your barrier system:

M16 x 50mm Armco Barrier Post Bolt – connects rails to posts
M16 x 35mm Armco Barrier Lap Bolt – connects rails together

These ensure a strong and secure installation.

Step 5: Add Corners

If your barrier changes direction, you’ll need corner sections:

More options can be found on the barrier calculator page. Corners allow your system to follow walls, bays, and layouts correctly.

Step 6: Add Barrier Ends

Finish your system safely with end sections:

More options can be found on the barrier calculator page. These reduce exposed edges and improve safety.
