In industrial plant projects such as chemicals, pharmaceuticals, dust workshops, and hazardous chemical warehouses, explosion-proof partition walls are a critical safety enclosure structure. Many overseas general project contractors and building materials purchasers are prone to pitfalls during the material selection stage. They simply look at the appearance quotation of the panels and place orders. However, during the on-site construction or acceptance process, they discover that the explosion-proof and fire-resistant indicators of the panels do not meet the project specifications, or the panels are deformed due to moisture, and the steel plates and core materials are delaminated, which directly slows down the progress of the entire project. Fiber cement composite steel panels, also often called steel-faced fiber cement panels and explosion-proof panels in the industry, are now the mainstream main materials for lightweight explosion-proof partition walls. Below we will talk about several key points that need to be controlled when selecting actual projects.
In industrial plant projects such as chemicals, pharmaceuticals, dust workshops, and hazardous chemical warehouses, explosion-proof partition walls are a critical safety enclosure structure.

However, during the on-site construction or acceptance process, they discover that the explosion-proof and fire-resistant indicators of the panels do not meet the project specifications, or the panels are deformed due to moisture, and the steel plates and core materials are delaminated, which directly slows down the progress of the entire project. Fiber cement composite steel panels, also often called steel-faced fiber cement panels and explosion-proof panels in the industry, are now the mainstream main materials for lightweight explosion-proof partition walls. Below we will talk about several key points that need to be controlled when selecting actual projects.
In the first step of selection, you must first clarify the risk level of the project, that is, the estimated explosion overpressure value and fire resistance limit requirements. Ready-made plate specifications cannot be directly applied. The fiber cement composite steel plate explosion-proof partition wall is not based on the plate itself, but a complete system, including panels, steel keels, anchoring components, and sealing accessories. For the same plate, with different keel spacing and steel thickness, the final anti-explosion pressure it can withstand is very different. If there are flammable and explosive materials in the factory, a risk assessment must be done first to determine the corresponding anti-explosion pressure, and then let the supplier do secondary structural design and select plate thickness and keel specifications, instead of just buying plates and assembling them yourself. Many purchasers tend to ignore this point, thinking that buying "explosion-proof panels" can meet all working conditions. In the end, the overall strength of the system does not meet the standard.
The second step is to verify the material and composite process of the board itself. The standard fiber cement composite steel plate structure is a composite galvanized steel plate on both sides of the fiber cement core material. The core material is high-pressure steam-cured fiber cement, and the combustion grade reaches A1 level non-combustible. When selecting, pay attention to the coating type of the steel plate. For indoor drying plants, electro-galvanized surface coating can be used, which is more cost-friendly. If the workshop has high humidity, corrosive gas, or a coastal factory area, priority is given to hot-dip galvanized steel plates, which will have much stronger anti-rust capabilities. Another key point is the composite bonding process. For poor-quality plates, the steel plate and core material are simply bonded. After long-distance shipping or on-site cutting and vibration, the steel plate is easy to bulge and peel off. When an explosion impact occurs, the plate will shatter and splash, causing secondary damage. Before purchasing, it is best to request a third-party testing report, apply for samples, and do simple bending and peeling tests to evaluate bonding stability.
Then make the choice based on the on-site environmental conditions. In addition to explosion-proof requirements, some factories also have thermal insulation and sound insulation requirements. In this case, you can choose an insulated explosion-proof partition with rock wool filling; if it is just an indoor partition and there is no need for thermal insulation, a non-insulated structure will be enough. In humid workshops and underground auxiliary workshops, you should also pay attention to the moisture content of the core material. High-density steam-cured core materials have lower water absorption and are less likely to absorb water, swell, and warp the board surface. The on-site processing performance of the plate is also worthy of attention. Qualified fiber cement composite steel plates can be drilled and cut on-site, but the galvanized layer at the cutting position must be protected to avoid rust on the cut.
Another point is the adaptation of documentation, packaging and export, which is especially important when purchasing for overseas projects. For special protective panels, you cannot just look at samples. Suppliers must provide complete test reports and product certificates to meet local building code review. When many overseas projects are accepted, the lack of compliance test documents will directly fail them. If it is an export order by sea, the panels must be waterproofed with a waterproof film + wooden frame packaging to prevent damage to the panels caused by moisture and collision in the container. For large-volume projects, it is recommended to test orders in small batches first to confirm the flatness and dimensional tolerances of the plates before arranging mass production.
Finally, we must distinguish between blast-resistant walls and blast-venting walls. These two types of wall materials cannot be mixed. Fiber cement composite steel plates are mostly used in anti-explosion partition walls, which are used to resist explosion shock waves and limit the explosion range; explosion venting walls are used to release pressure, and the logic of material selection is completely different. Many buyers confuse the functions of the two, and choosing the wrong material will bring huge safety risks. When selecting suppliers, give priority to factories that have similar overseas factory project cases and have the ability to deepen structures. They not only sell panels, but also provide supporting installation suggestions.
In general, the core of fiber cement composite steel plate explosion-proof partition wall selection is not to select the most expensive plate, but to match the project's explosion risk, fire resistance requirements, and on-site environment, while also verifying the plate process, inspection documents, and supporting design of the entire system.
