We design and manufacture a full range of flatdeck solutions, including truck decks, semi-trailers, full trailers, and B-trains, purpose-built for New Zealand’s demanding freight conditions. Engineered for strength, versatility, and durability, TMC flatdecks handle everything from general freight and containers to machinery, steel, timber, and oversize loads.
Robust, Lightweight Construction
Engineered using high-tensile steel, laser-cut profiles, and finite element analysis (FEA) to deliver exceptional strength and durability while keeping tare weight to a minimum.
Low Neck Height
Improves stability and maximises load height for high-cube containers.
Versatile Configurations
Available as truck decks, semi-trailers, full trailers, or B-trains with optional container twist locks.
Nationwide Service Support & Warranty
Backed by TMC’s own workshops in Auckland, Hamilton, and Christchurch, plus authorised service agents across all main centres. We also operate a full online parts store with fast nationwide delivery of genuine TMC trailer components, keeping your fleet moving with minimal downtime. Every TMC trailer is covered by our 2-year, unlimited-kilometre warranty, giving you total confidence and support long after delivery.
Stock Availability
Popular models including quad semi’s, are held in stock for quick delivery and can be finished in your fleet colours within weeks.
Chassis & Deck Options
Thin-neck or step-deck chassis for variable fifth-wheel heights or lower load decks, high-tensile steel or shiplapped hardwood deck materials, in-deck chain boxes, effluent tanks, or beaver tails for light-vehicle loading, longitudinal deck stiffeners for trolley jacks and vehicle transport and sidelifter footpads.
Headboards & Load Retention
RHS open-style, steel-plated, or fold-down headboards, upright stanchions, heavy-duty stanchions for pipe or concrete work, and trestles/crossbars for specialised freight
Running Gear & Suspension
Axle and suspension options from ROR, Jost, SAF, BPW, and Hendrickson
Guards & Accessories
Plastic or polished aluminium full guards, with stainless infill strips between ribs, toolboxes, dunnage boxes, and cover boxes available as well as overwidth signage, spare-tyre carriers, and strap-stowage racks
Under New Zealand’s Vehicle Dimensions and Mass (VDAM) Rule, standard length limits are 20 m for a truck and full trailer, 19 m for a truck and semi-trailer, and 20 m for a B-train. With a High Productivity Motor Vehicle (HPMV) permit, these limits can extend up to 23 m for B-trains or full trailers, and 19.45 m for semi-trailers, with Gross Combination Mass (GCM) exceeding 50 tonnes depending on axle configuration and approved routes.
Container (Overweight/ISO) Permits allow operators to legally move heavier import/export containers beyond standard weight limits, while HPMV permits are generally used for domestic freight. Typical legal setups include around 39 T GCM for a 6×4 tractor with a tri-axle skeletal, and up to 44 T GCM for an 8×4 tractor with a quad-axle, giving payloads of roughly 24–26 tonnes — or around 30 T gross with a permit.
Permits are issued by Waka Kotahi NZTA (for state highways) and local councils (for local roads) through the NZTA Permit Portal. TMC flatdecks are built to meet full HPMV compliance, with optimised axle spacing, chassis geometry, and tare weight to maximise legal payloads.
Super Single 22.5” Tyres (wide single tyres)
✅ Lower tare weight – fewer rims, tyres, and bolts reduce overall trailer weight
✅ Less rolling resistance – improves fuel economy and slightly reduces CO₂ output.
✅ Simpler maintenance – only one tyre per hub to check and replace.
✅ Better tracking – fewer scrub forces on corners, reducing tyre wear on tri-axle setups.
19.5” Dual Tyres
✅ Higher load tolerance per axle – twin tyres spread the weight, ideal for heavy or uneven loads.
✅ Redundancy – if one tyre fails, the other can support the axle temporarily.
✅ Lower deck height – smaller diameter tyres reduce overall trailer height.
We carry stock units for immediate delivery, and can often paint and fit these in your fleet colours within just a few weeks.
For urgent jobs or common configurations, we can usually get you on the road quickly.
If you have a specific deadline or spec, talk to us, we can often fast-track production or allocate an in-stock chassis to suit your needs.
TMC trailers are backed by nationwide after-sales support through our own workshops in Auckland, Hamilton and Christchurch and authorised service agents in all main centres. Our team provides warranty repairs, servicing, and genuine parts to keep your trailer on the road and performing at its best.
