I have recently bought a large quantity of 47.6 mm dia.x1.2mm wall thickness steel tube in 6.7M lengths.This is spotbar size and can use scaff clamps.At $15 a length it is an oppurtunity to make a very cheap grid or rack.I also have black 6mm braided polyproylene rope(sash cord but much stronger and it does not rot) at $160 a 250M roll.David Ashton 92728942.
