Futura Box-Beam sizes and specs

Futura Box-Beam is a high tensile, galvanised steel profile, roll formed into a fully enclosed rectangular hollow section. It is used for rafters, purlins, girts and other structural applications in steel framed buildings. It comes in nine standard Box-Beam sizes from 150mm to 540mm high, designed and made in Cambridge, New Zealand.

What is Futura Box-Beam?

Futura Box-Beam is a world first, gravity-defying steel framing technology. It is the steel framing behind every Futura NZ steel building.

Clearspan and lightweight

The rectangular hollow section gives a strong, lightweight beam that clear spans long distances, so you get usable open space inside the building.

Fully enclosed and bird-proof

The enclosed profile gives birds no place to land or nest, so the roof structure stays clean and hygiene-friendly. There are no open C-purlins, and Futura’s knee and apex connections are clean and bird-proof too.

Patent-pending joining method

Futura Box-Beam uses a unique, patent-pending joining method. Each member is rolled from a single strip width, which gives the beam its integrity.

Supplied as a complete structure or as purlins

Box-Beam can be supplied as a complete structure or as Box-Beam purlins only to integrate with traditional steel buildings.

All Futura steel is produced to standard AS1397:2011. It is high-tensile, from grade G450 up to G550. It is available with galvanising for many applications and with high-durability metallic coatings for exterior and coastal applications.

Box-Beam spans and uses

Futura Box-Beam can achieve significant clear spans. The span depends on environmental loadings, and longer spans are possible with additional design elements.

Design and supply support

Futura helps with advice, design and supply. That includes cost comparison, design efficiency, fire design, building planning, infrastructure needs analysis and material selection.

We provide Revit and BIM models with the bill of materials taken from the plans, plus 3D modelling, renders, and engineering automation and approval. Box-Beam is delivered by Hiab to site nationwide, in full and on time, with construction advice.

 

Frequently asked questions

What sizes does Futura Box-Beam come in?
There are nine standard sizes, from 150mm to 540mm high. Widths range from 65mm to 125mm, and the codes run from FB15008 to FB54020.
What steel grade is used in Futura Box-Beam?
All Futura steel is produced to standard AS1397:2011. It is high-tensile, from grade G450 up to G550.
Is Futura Box-Beam galvanised?
It is available with galvanising for many applications and with high-durability metallic coatings for exterior and coastal applications.
How far can a Futura Box-Beam span?

Futura Box-Beam can achieve significant clearspans. The span depends on environmental loadings, and longer spans are possible with additional design elements. For detailed calculations and proven use cases, talk to our team.

Is Futura Box-Beam bird-proof?

Yes. The profile is fully enclosed, so birds have no open sections to nest in, and Futura’s knee and apex connections are bird-proof, too.

Can Futura Box-Beam be used with structural steel or timber framing?

Yes. Box-Beam can be used as a full portal structure or as purlins integrated with structural steel or timber framing. It can also be used for full roof structures on timber poles.
