Adjustable Side Guard Tuber

Description

Product Core Introduction
Structural design: It adopts a specially customized hollow aluminum alloy square tube structure with embedded card slots, which is extruded into one piece. The profile comes with preset matching card slots, which can be quickly assembled with the matching adjustable brackets and protective crossbars without additional complex hole processing, greatly reducing installation difficulty.
Performance advantages: Compared to traditional steel guardrail profiles, it has a lighter weight and does not significantly increase the overall load capacity of the vehicle. At the same time, the aluminum material itself has natural rust and corrosion resistance properties. After surface treatment, it can withstand the erosion of outdoor rain, snow, salt and alkali road conditions for a long time, without the common problems of rust, powdering, and cracking of ordinary steel guardrails, and its service life is greatly extended.
Adaptation features: Standardized profile specifications support flexible cutting, coupled with adjustable installation structures, can adapt to different wheelbases and chassis layouts of vehicle models, easily adjust the installation position of protective barriers, and meet the compliance requirements of national standards for the ground clearance height and spacing of commercial vehicle side protection.
📌 Main usage scenarios
In the field of freight commercial vehicles, it is a specialized main body profile for the side guardrails of semi-trailer trucks, box type transport vehicles, tank trucks, and refrigerated trucks. It is used to make the protective structure of the vehicle’s side to prevent pedestrians and non motorized vehicles from accidentally getting caught in the bottom of the vehicle. At the same time, its lightweight characteristics can also help reduce the vehicle’s self weight, improve its effective cargo capacity, and meet the compliance requirements of annual inspections of freight vehicles.
Special vehicles and modification scenarios: can be used for customized modification of side protection for engineering work vehicles, sanitation vehicles, and recreational trailers, flexibly cutting and adapting to the protection needs of special body structures. It can also be used as a lightweight side mounting substrate to fix accessories such as on-board toolboxes and extended storage racks, balancing protection and practical expansion.

Pre-installation preparation
Check the length of the profile in advance, cut the profile according to the actual needs of vehicle side protection, clean the aluminum shavings and burrs in the profile slot, and at the same time clean the installation base surface on the vehicle chassis side to remove oil stains and protruding debris.
Prepare the matching adjustable bracket, stainless steel fastening screws, electric drill, level ruler, tape measure and other tools, confirm that the clamping structure of the profile and bracket is completely matched, and there is no deformation or misalignment problem.
2、 Pre installed alignment
Insert the cut aluminum alloy profile into the connecting slot of the adjustable bracket, and use the preset slot provided by the profile to complete the initial splicing. There is no need for additional large openings, only mark the drilling position at the locking point.
Referring to the national standard for side protection requirements, the overall position is preliminarily adjusted, and the reference height of the profile is marked to ensure that the lower edge of the profile is not more than 55cm above the ground after subsequent installation is completed, and the overall position is parallel to the side of the vehicle.
3、 Fixed locking
Drill holes at the marked points and use stainless steel fastening screws to completely lock the profile and bracket. When locking, use diagonal tightening sequence to avoid local deformation of the profile under stress.
Synchronously adjust the angle and extension distance of the bracket, use a level to verify the flatness of the profile, control the height deviation of the profile within 5mm, and ensure that the entire side guardrail has no visible tilt.
4、 Debugging and verification
Manually push and pull the entire profile to confirm that there is no looseness or shaking between the profile and the bracket, and that all locking points are securely fastened in place.
Final verification of protective parameters: Confirm that the distance between the front and rear ends of the profile and the outermost edge of the vehicle’s front and rear tires does not exceed 30cm, and that all protective clearances meet the compliance requirements for commercial vehicle side protection, in order to avoid any non-compliance issues during subsequent annual inspections.
Clean the installation scratches on the surface of the profile, and perform simple waterproof treatment at the joint gaps to prevent water vapor from infiltrating the gaps and causing local oxidation, thereby extending the service life of the profile.
