Introduction

Whether you are building a new truck body, maintaining a fleet or sourcing aftermarket parts, understanding what each product category is and how to choose the right components saves time, money and downtime. This guide explains Ganland's 13 core product categories - what each one is, what it does, and the key selection criteria for each.

1. Cam Door Locks (Trailer Truck Rear Door Lock)

What they are: Truck trailer cam door locks are the standard rear door locking system for van bodies, box trucks and semi-trailers. A handle turns a locking rod fitted with cams at top and bottom that engage keepers on the door frame.

How to choose: Ganland manufactures cam door locks for 16mm, 21mm, 27mm and 34mm pipe systems in zinc-plated steel and 304 stainless steel. Choose 27mm for standard trailer rear doors, and 304 stainless steel for refrigerated, coastal or high-corrosion applications.

2. Toolbox Locks & Latches (Toolbox Serie)

What they are: Truck toolbox locks secure storage compartments on trucks and trailers. The series includes aluminum toolboxes, paddle locks and T-handle latches.

How to choose: Ganland offers 304 stainless steel paddle locks with polished finish, flush-mount slam locks with key access, and folding T-handle locks for tool boxes, doors and cabinets. Choose key-unlock paddle locks for security-sensitive storage and flush-mount designs for aerodynamic exterior profiles.

3. Truck Door Hinges

What they are: Truck door hinges carry the weight of rear and side doors through thousands of open-close cycles.

How to choose: Ganland manufactures steel, galvanized steel and 304 stainless steel hinges from 6 to 12 inches, with bolt-on mounting for easy replacement. Heavy steel doors typically need 3-4 hinges per door, while lighter aluminum doors need 2-3. Choose 304 stainless steel for reefer, marine and food transport applications.

4. Fastener Series (Fastener Serie)

What they are: Truck fastener hardware includes toggle latches, spring bolts, shoot bolts and door retainers used to secure doors, panels and hatches on truck bodies.

How to choose: Ganland produces zinc-plated steel and stainless steel fasteners with spring-loaded mechanisms for smooth operation. Toggle latches suit adjustable-tension applications, while spring-loaded shoot bolts are ideal for slam-action door securing.

5. Cargo Control Systems

What they are: Cargo control systems secure loads inside trucks and trailers, including tie-down rings, strap assemblies, cable winches, cargo bars and E-track systems.

How to choose: Ganland supplies galvanized E-track with 50,000 psi yield strength, forged steel tie-down rings and heavy-duty winches. For floor or wall mounting, pair E-track rails with compatible tie-down rings and cargo bars to create a complete load securement system.

6. Curtain Side Trailer Parts

What they are: Curtain side trailer parts keep tautliner systems operating smoothly, including rollers, buckles, straps, tensioners, PVC tarpaulin and track profiles.

How to choose: Ganland is an original manufacturer of curtain side rollers with ball bearing wheels, over-center buckles, ratchet tensioners and 900 gsm PVC-coated polyester tarpaulin. Rollers should be spaced every 400-500mm along the top hem; choose sealed ball bearing rollers for 2-4 year service life.

7. Semi-Trailer Parts

What they are: Semi-trailer parts cover the full range of body hardware for semi-trailers, including door locks, hinges, fasteners, mudguards and cargo control systems.

How to choose: Ganland provides complete component sets for semi-trailer bodybuilding and maintenance, with custom manufacturing to technical drawings. Specify parts by trailer type (curtain sider, box, refrigerated or flatbed) and by component material to match the trailer's operating environment.

8. Rubber Bumpers & Buffers

What they are: Rubber bumpers and buffers absorb impact and prevent metal-to-metal contact on truck doors, tailgates and dock areas.

How to choose: Ganland produces solid rubber, EPDM and polyurethane buffers with 60-90 Shore A hardness. Door stop buffers limit door over-travel, while dock bumpers are steel-reinforced for heavy impact. Choose EPDM for outdoor and refrigerated applications, and polyurethane for high-abrasion floor zones.

9. Trailer Mudguards

What they are: Trailer mudguards protect cargo, chassis components and following vehicles from road spray and stone damage.

How to choose: Ganland supplies heavy-duty rubber mudguards with mounting brackets in universal fit designs. Rubber construction provides UV and weather resistance with flexible impact absorption. Match the mudguard width to the tyre width and choose bolt-on bracket designs for simple replacement.

10. Truck Door Seals

What they are: Truck door seals prevent water, dust and air ingress around rear and side doors of van bodies and trailers.

How to choose: Ganland offers EPDM, PVC and sponge rubber seals in P, D and E profiles with push-on, adhesive-backed and screw-on installation. EPDM is the industry default with -40C to +120C temperature resistance. For reefer bodies choose EPDM or silicone with screw-on retainers to stay in place at low temperatures.

11. Refrigerated Truck Body Parts

What they are: Refrigerated truck body parts include door locks, handles, hinges, seals and hardware designed for reefer and freezer bodies.

How to choose: Ganland produces 304 stainless steel cold room hinges, cam locks and handles that withstand -30C temperatures, humidity and cleaning chemicals. Stainless steel is essential in reefer applications because standard zinc-plated hardware corrodes rapidly under cold-room condensation and wash-down cycles.

12. Edge & Corner Protectors

What they are: Edge and corner protectors shield the most vulnerable points of truck bodies from dock impact, tree branches and handling damage.

How to choose: Ganland supplies aluminum and steel corner caps, rubber corner guards and aluminum edge trim profiles. Use aluminum caps on top rear corners, steel or heavy aluminum at floor corners where dock impact occurs, and rubber guards where flexible impact absorption is needed.

13. Excavator Body Parts

What they are: Excavator body parts include cabs, engine hoods, toolboxes, doors and panels for construction machinery.

How to choose: Ganland manufactures aftermarket sheet metal and body components for Komatsu, CAT, Hitachi, Doosan and Kobelco excavators, produced to OEM specifications with custom manufacturing available. When ordering aftermarket parts, provide the machine model and serial number to ensure correct fitment.
