How should you choose HOWO or SHACMAN dump-body floor steel and thickness?

Choose a HOWO or SHACMAN dump-body floor by its documented steel grade, plate thickness, support design and intended load. A thickness figure alone cannot establish resistance to wear or loading damage. Ask the body builder to justify the complete specification for your material and loading method, then agree how it will be verified before shipment.

Start with the proposed HOWO or SHACMAN dump truck, including its chassis and finished body. Do not assume a body shown on another truck has the same floor, steel or reinforcement. The purchase specification should identify the actual construction offered.

Describe the load before asking for millimetres

Give the supplier a description of what enters the body. Sand, crushed aggregate, excavated soil, demolition rubble and large angular rock are different duties. Include the largest expected pieces, whether sharp material is common, and whether loads contain wet or sticky material. Photographs of representative cargo can clarify a description such as quarry work.

Explain the loading equipment and normal loading practice. Material placed near the floor is a different impact condition from material dropped into an empty body from height. Ask the body builder to consider the loading conditions in its proposal. This is a specification discussion, not permission to exceed the truck's approved load or the site's safe loading procedure.

An operator discussion about relining a worn dump body asks what steel thickness would be sufficient. It illustrates the question buyers need to settle; the repair suggestions concern individual trucks and are not a HOWO or SHACMAN design standard.

Separate steel grade from plate thickness

Request the grade and nominal thickness for the floor, sides, front wall and tailgate separately. Also ask whether there are additional liners or wear strips. A description such as heavy-duty steel leaves important questions unanswered, including which material specification the builder will supply.

Mild steel and a specified wear-resistant grade cannot be compared by thickness alone. SSAB's explanation of mild steel and Hardox wear steel describes how a change of material can allow a different body design and reduced plate thickness. That is a design possibility, not proof that an unspecified thinner floor is suitable.

If a quotation names Hardox or another branded steel, ask for supporting material documentation tied to the supplied body. A brand name in a message does not verify the installed plate. Ruidite availability and the proposed grade must be confirmed for the individual order; this guide does not claim every truck uses branded wear steel.

Examine the floor as part of the body

Ask for a drawing or clear description of the floor supports, crossmembers, mounting arrangement and any reinforcement. Have the builder explain how these work with the proposed plate and intended cargo. Approving only the visible thickness leaves the rest of the construction undefined.

Wear may also be uneven. SSAB's guidance on localized side-wall wear discusses concentrated wear along vertical weld lines. Its point is relevant when reviewing fabrication details: the condition of one convenient measurement point cannot describe the whole body.

For a refurbished truck, establish whether the body is retained, repaired or replaced. Request photographs of the existing floor and underside before cosmetic preparation where available. Ask which patches, liners and structural repairs remain. A new layer over an old floor needs an assessment of the underlying structure, attachment and added mass; it should not be described simply as a new body.

Keep extra steel in the weight calculation

Compare finished truck weights, not only body dimensions. Additional floor material, reinforcement or a liner contributes to tare mass. With the same permitted gross mass, a heavier completed vehicle leaves less mass available for cargo, subject also to individual axle and tyre limits.

For a hypothetical comparison, suppose two otherwise equivalent completed trucks weigh 15,000 kg and 15,400 kg. At the same applicable gross limit, the heavier truck has 400 kg less gross-weight headroom. These invented figures explain the arithmetic only. They are not Ruidite product weights, legal limits or a promise that either truck can carry a particular load.

Use the body-size and payload guide for the separate volume calculation. Confirm local weight requirements for the destination and route. A stronger floor does not increase an axle rating or create permission to overload.

Agree the acceptance evidence before ordering

Put the proposed construction in the order attachment so the buyer, builder and inspector use the same description. Include:

• Intended materials, largest pieces and loading conditions.
• Specified plate grade and thickness for each body section.
• Any liner, wear strips, reinforcement and floor support details.
• Whether the body and its components are new, retained or repaired.
• Available material identification and supporting documents.
• Finished weight evidence and the agreed inspection scope.

Have a competent inspector agree a suitable thickness measurement method, locations and treatment of coatings. Record readings against those locations rather than accepting a photograph of a measuring tool with no identified position. Nominal plate thickness, remaining thickness on a worn floor and total thickness through overlapping material are different observations.

The inspection should also assess the body condition, supports, attachments and visible repairs under an agreed scope. Thickness measurements cannot establish steel grade by themselves. Where documentation or access is insufficient, record the gap and resolve it before accepting the claimed specification.
