BX Chassis Tech Brief

Tech Brief

Inter-Row Spacing & Edge Clearances

Flat Roof Attachment Anchors

BX Systems can be fully ballasted, fully

anchored, or a hybrid optimized for the site.

Combine BX with an IronRidge Flat Roof

Attachment Kit to eliminate hundreds of

pounds of required ballast weight and

achieve congurations as light as 3 PSF.

The placement and fastening method can

be optimized for existing roof structures,

and pre-approved membranes are offered

to maintain membrane roof warranties.

Testing & Certication

Design Assistant

Automated design software provides an accurate bill of materials, using a simple drag-and-draw interface to

generate a complete system plan—also generate a ballast map showing the required ballast for each Chassis.

Permit Documentation

Design Assistant project reports are backed with a ASCE/PE stamp and Commercial Services are also

available to assist with more complex projects. Visit our website or contact an IronRidge sales represenative.

UL 2703

Certication for the BX System conforms to the latest requirements and includes 1) Mechanical, 2) Bonding,

and 3) Class A Fire Ratings (without wind deectors). Ninety percent of solar modules are fully supported.

5° Chassis

10° Chassis

With 10-13” inter-row spacing, BX provides an 8-10% increase in power density compared with other ballasted

systems—that’s a capacity increase of 20% in a typical 50kW system. The BX Chassis geometry also offers

more than 5” of clearance in the 10-degree conguration and 8” in the 5-degree conguration, enabling the

system to avoid drain domes, roof saddles, and conduit supports.
