THE

SPECS

The main design feature of the trailer frame is the 5mm, 350* grade steel, C-Section Channel that runs the full length of the trailer allowing the sub frame to flex and move as it negotiates rough off road terrain.

The chassis is made of Laser Cut, CNC folded, open chassis members allowing for easy wash down and cleaning, with no enclosed areas where mud, sand and salt can get trapped and cause corrosion.


*350 grade is higher tensile steel. Box Section is 300 grade and most C sections are 300.

CANOPY CONSTRUCTION

The Mounting system of a Builders Trailer.

Builders Trailer Spring Mounting System

Our unique mounting system reduces the shock/vibration distributed to the Aluminium canopy from the road conditions and is absorbed through this unique engineered mounting system. This reduces stress on the canopy, dramatically reducing cracking and fatigue over time.

2.5mm Aluminium fully Welded Monocoque Design

The canopy is fully monocoque, forged with CNC Laser Cut and folded with 2.5mm aluminium plate.

Precision Laser cut and CNC Folded components

The entire canopy is designed to be laser cut and CNC folded to optimal accuracy. 

Internal sheet metal bracing for added rigidity around door openings

The internal sheet metal bracing gives added rigidity for the doors and the internal structure of the canopy. This allows the canopy to support more load on the outside of the trailer, and protect the inside.

Reinforced side-opening doors.

The reinforced, side-opening doors of the builder's trailer canopy have 2-point anti-theft locking for safe and secure equipment storage. These doors are fully sealed and are dust and watertight.

Pinchweld sealed door opening with a full-length hinge.

The canopy doors are fitted with a pinchweld seal around the full opening and are secured via a full length hinge on the topside.

High-tensile fasteners and structural grade rivets

Securing the doors and internal components of the service trailer are high-tensile fasteners and structural grade rivets.
