Welcome to Trailercad
About us
Trailercad is an independent engineering team specializing in semi-trailer, industrial machine and steel structure design. With a combined 30+ years of hands-on experience, we support manufacturers and entrepreneurs across both light-weight and heavy-duty trailer segments.
From light-weight campers and aluminum utility trailers to high-capacity road and port trailers—we bring practical insight, CAD precision, and design compliance into every projects.
Light Weight Trailers
We specialize in light-weight trailers that balance durability and agility. These include teardrop campers for adventure seekers, food trailers and box trailers designed with space efficiency in mind, aluminum utility trailers for lightweight strength, and DIY-friendly trailer kits for custom builders. Our models are optimized for performance and easy assembly.
Heavy Duty trailers
For heavy-duty applications, we design high-capacity road and port trailers that meet international safety standards. Our portfolio includes skeleton trailers, flatbeds, tankers, side tippers, and extendables for road transport, as well as bomb cart trailers, terminal trailers, and roro trailers built for demanding port environments.
Other Products
In addition to trailers, we provide custom engineering solutions for specialized industrial machines and equipment. Our expertise extends to designing material handling systems, manufacturing machinery, and other innovative products that align with client needs.
Whatever your project demands, Trailercad delivers designs that are smart, manufacturable, and built to last.
Custom semi trailer designs & innovations
We specialize in designing custom semi-trailers that align with both client specifications and industry standards. Our designs incorporate innovative features that enhance durability, performance, and ease of manufacturing. Whether it’s a lightweight teardrop camper or a high-capacity road trailer, we ensure every detail is optimized for efficiency and compliance.
Engineering calculations & FEA analysis
Structural integrity and safety are at the heart of our designs. We perform detailed engineering calculations and Finite Element Analysis (FEA) to evaluate stress, deflection of the structure, load distribution, and overall performance. Our analyses help prevent failures and ensure that your trailer meets rigorous safety standards while maintaining optimal weight and strength.
Road regulation compliance support
Navigating road regulations can be complex, but we simplify the process by ensuring all designs comply with relevant standards and laws. Whether it’s Australian Design Rules (ADR), European standards, or other local regulations, we provide expert guidance and documentation to secure approvals and keep your project on track.
