Industrial Tube Ag-Beam is widely regarded as the cost-effective alternative to wooden and wire 

Ag-Beam is for those who demand quality product, quality service and long-term benefit that offers:

  • Lightweight hollow section Galvanised beam, purpose made to support Kiwifruit and other
    load bearing horticultural crops.

    smooth surface preventing insect or fungus accumulation. Much stronger and lighter than 
  • Simple joining methods using slip on galvanised sleeve.
  • Significant (60%) savings on time and labour over conventional timber pergola.

Industrial Tube Ag-Beam is manufactured using either a 1.15mm or 1.55mm Pre Galvanised 
base material sourced from New Zealand Steel. It is then shaped into a hollow section with 
outside dimensions of 63mm x 37.6mm. The finished product has Tensile Yield strength of 
350MPA minimum, and a total Zinc Coat weight of 450 grams per square metre shared over 
both external and internal surfaces.

ITM Joiner is also made in two wall thicknesses 1.55mm (Standard) and 1.85mm (Heavy) 
with the same performance specifications as Ag-Beam. Both sizes are designed to simply 
slide over the Ag-Beam as a connecting sleeve.

ITM Joiners are Precision-cut to 400mm lengths and delivered in palletised bundles. Other 
lengths can be manufactured to meet specific requirements, especially where longer Joiners 
can provide additional load capacity.
