Guide · for the trade
A clear specification avoids surprises on site and in the budget. This guide covers everything you need to specify planter boxes with confidence — and the resources we provide to make it easy.
Specify architectural aluminium for most projects — light, corrosion-resistant and finishable in any colour — with gauge and bracing scaled to size. See aluminium vs Corten and benefits of aluminium.
Call up the powdercoat colour, sheen and texture (and any Colorbond/Dulux match). We hold finish consistency across the whole job. Finish samples are available on request.
Specify base type (open/closed), drainage outlets, falls and liners — critical on structures and rooftops to protect waterproofing.
For elevated work, specify to saturated weight within the engineer's allowance — we provide unit and saturated weights. See rooftop weight & load.
We provide CAD/DWG/DXF files, specification sheets, shop drawings, QA documentation and warranty information through the Documentation — everything needed to specify and document.
Australian-made suits tight programs, oversize and one-off pieces; the imported range suits project quantities at value. Both are designed by POBOX to the same standard. Why AU made · Why imported.
