Frequently Asked Questions
Got questions about Spanmor products, installation, or compliance? We’ve answered the most common ones here to help you plan with confidence.
Can a Spanmor aluminium post be used with timber beams?
Our durable posts are designed specifically to work as part of a complete engineered framing system with Spanmor aluminium beams and connectors to ensure structural integrity.
How do I choose between a 90mm and 115mm post?
The 90x90 aluminium post is ideal for compact residential structures attached to a house, while the 115mm post offers increased capacity for freestanding structures and subfloor systems.
Are these posts suitable for coastal environments?
Yes, they are manufactured from high-strength, corrosion-resistant aluminium, making them far more durable than steel or timber in coastal areas.
Do I need specific connectors for installation?
Yes. Suitable top and bottom connectors are selected based on the structure type, fixing method, and load requirements.
Can I use the 150mm post for residential carports?
Absolutely. The 150mm post is designed for heavy-duty applications and feature outdoor structures requiring increased load capacity and a bold visual presence.
Are Spanmor aluminium posts supplied as standalone items?
No, they are not supplied as standalone products. They are engineered to work as a system to ensure correct load transfer and compliance.
Does an aluminium post require regular painting?
No. The powder-coated aluminium finish is low-maintenance and does not require the regular repainting or staining associated with timber posts.
