They are bolted together in three sections for easier transportation
This one is 2/3 size as B&Q don't sell 7 foot long sheets of ply. One sheet of 1800 x 600 x 6mm ply will make exactly three beams this way and we need a load of them so accuracy has been sacrificed for budget in this instance. I used their free timber cutting service

Ply is glued screwed into timber struts for strength and end caps are glued on

Screws are countersunk, filled and sanded

Reinforcing plate is cut from MDF. Polystyrene balls from a craft shop are used to make rivet heads

Beams are sprayed with matt brown paint, sprinkled with dry sand and resprayed. Bright orange spray paint is lightly dusted over giving a corroded, rusty look to the beams

Assembled

The milky colour is a wash of matt varnish that hasn't quite dried. I wanted to get rid of the slight sparkle that the sand was giving in bright sunlight

Barbed wire is green garden wire with barbs made of speaker cable and painted up
