What Is 5052 H32 Aluminum Coil?
5052 H32 aluminum coil is a non-heat-treatable 5xxx series Al-Mg alloy supplied in a strain-hardened and stabilized temper. It combines higher panel strength than common 3xxx body sheet with the bending, profiling and roll-forming performance required for commercial vehicle production.
Shandong Union supplies 5052 H32 wide coil for truck bodies, trailer roofs, refrigerated vehicles, insulated panels and other large-format enclosures. Extra-wide material allows larger roof and side-wall sections to be formed with fewer joints, helping simplify fabrication, sealing and continuous OEM production.
Regular vehicle-body thicknesses include 0.7, 0.8, 1.0, 1.2, 1.5 and 2.0 mm. Width, coil dimensions, unit weight, flatness, cut-to-length size and coating color can be supplied according to confirmed production requirements.

5052 H32 Material & Temper
5052 is an Al-Mg alloy with magnesium as its principal alloying addition. The H32 temper is strain hardened and stabilized to provide a practical balance of strength and formability for vehicle-body panels.
For truck and trailer manufacturing, H32 is suited to components that must retain their shape after forming and withstand road vibration, cargo contact and outdoor service. It supports bending, profiling, rib forming and edge forming for large roof and side-panel production.
Chemical composition and certified mechanical properties are controlled according to the applicable material standard and order specification. For engineering approval, request the Mill Test Certificate corresponding to the required thickness and width.

Why Choose 5052 H32 for Truck & Trailer Bodies?
Commercial vehicle panels must remain workable during fabrication while resisting repeated loading, road vibration, moisture and daily cargo handling. 5052 H32 provides a useful combination of panel strength, formability and corrosion resistance for these operating conditions.
Higher Panel Strength
The Al-Mg alloy provides higher structural strength than common 3xxx body sheet, supporting side skins and enclosure panels exposed to cargo contact and regular handling.
Stable Forming
H32 retains the formability required for bending, profiling, rib forming and edge forming without moving to an excessively hard temper.
Corrosion Resistance
5052 performs well in wet, humid and coastal environments, supporting long-term outdoor use for truck and trailer bodies.
Improved Dent Resistance
Higher panel strength helps resist local dents and deformation caused by cargo contact, loading operations and normal service loads.
Extra-Wide 5052 Coil for Reduced-Joint Trailer Roofs
Roof joints are a practical concern in box-truck, trailer and refrigerated-body production. When the required roof width can be covered by one continuous coil width, the roof skin can be formed with fewer transverse or longitudinal joints.
01 Fewer Roof Joints
A wider continuous strip reduces the need to join multiple narrow sheets across the roof structure.
02 Simplified Roof Sealing
Fewer joints mean fewer interfaces requiring sealing, helping simplify waterproofing and reduce potential leakage points.
03 Large-Format Forming
5052 H32 wide coil supports bending, profiling, rib forming and edge forming used in common vehicle-roof production.
04 Efficient Body Production
Continuous wide material reduces sheet positioning, joining and seam-treatment operations for batch and long-term OEM supply.
5052 Aluminum for Trailer Roofs & Side Panels
5052 aluminum is a reliable material for trailer roofs and side panels, offering an excellent balance of strength, low weight, and corrosion resistance. It performs well in rain, humidity, and road-salt conditions, helping extend the trailer’s service life while reducing overall vehicle weight. The alloy is also easy to bend, form, and weld, making it suitable for a wide range of trailer designs. Available in mill finish, embossed, or coated surfaces, 5052 aluminum is widely used for cargo trailers, enclosed trailers, and specialty vehicles.
Extra-Wide 5052 H32 Coil for Trailer Roofs
Extra-wide 5052 H32 coil is intended for box trucks, refrigerated trucks and insulated vehicle roofs where large continuous sections are preferred. It supports profiling and forming while reducing the number of roof joints.

Color-Coated 5052 H32 Sheet for Side Panels
For exterior side walls, 5052 H32 can be supplied with polyester or PVDF coating according to project requirements. The high-strength substrate supports body-panel rigidity, while the coated surface provides the specified appearance and weather protection.

5052 H32 vs. 3004 Aluminum for Trailer Bodies
Both alloys are used for commercial vehicle panels, but they serve different performance and cost priorities. Selection should consider strength, formability, dent resistance, service environment and the finished panel design.
| Selection Factor | 3004 | 5052 H32 |
| Alloy System | Al-Mn | Al-Mg |
| Strength | Moderate | Higher |
| Formability | Very Good | Good |
| Dent Resistance | Suitable for general body panels | Better suited to higher-load panels |
| Corrosion Resistance | Good | Very Good |
| Formed Roof Panels | Suitable | Suitable |
| Heavy-Duty Body Panels | General Use | Preferred |
| Material Cost | Lower | Higher |
Choose 3004 for cost-sensitive body panels where very good formability and general outdoor performance are sufficient. Choose 5052 H32 when higher panel strength, dent resistance and durability are more important, especially for refrigerated, logistics and higher-duty vehicle bodies.
