An 18mm GRP sandwich panel is often treated as a commodity, but relying on thickness alone to predict load capacity is a structural mistake. The panel’s ability to handle point loads and span distances depends almost entirely on the stiffness of the core and the laminate of the outer skins. If you misjudge these variables,…
An aluminum sandwich panel with a foam core works like an I-beam — thin aluminum skins carry structural loads while the low-density foam core between them handles insulation. That structural efficiency is exactly why these panels have moved from industrial warehouses into office facades, cold storage, and clean rooms. But the foam core is where…
Specifying a building sandwich panel requires more than checking the R-value on a spec sheet. Most procurement teams treat panel cores as interchangeable line items, but swapping PIR for mineral wool changes your entire fire compliance strategy. Standard PE or PU cores lack inherent fire resistance and require special treatment to meet codes, unlike Mineral…
A standard drop-weight test in a controlled lab rarely predicts how a panel behaves when a forklift clips a refrigerated truck body at -20 degrees Celsius. Most engineers focus solely on the initial impact energy absorption, yet the real failure point in CFRT composites is often the bond line integrity post-impact. Our recent data on…
Selecting the right core material is rarely about picking the lightest option. It is a calculated tradeoff between shear modulus and lifecycle cost, especially when balsa core panels are the default for marine decks. End-grain balsa offers impressive structural properties at a nominal density of 150 kg/m³ with a compressive strength of 12.8 MPa. However,…
Livestock buildings eat metal panels alive. You might assume wind or snow is the primary threat to your envelope, but inside a confinement barn, the air is chemically weaponized against your structure. Ammonia creates an electrochemical reaction that rots standard panels from the inside out, yet many specifications still treat agricultural insulated metal wall panels…
Specifying the wrong acoustic solution is a fast track to failed inspections. Project managers frequently demand soundproofing when they actually need sound absorption, leading to expensive rework and lost time. RaxPanel manufactures aluminum insulated ceiling panels designed as inner coatings for corrosive environments like chemical plants, where the material must reinforce the room against heavy…
Specifying the wrong surface material does not just hurt your budget, it forces facility shutdowns when hygiene protocols fail. You might assume a high-pressure laminate surface is sufficient, but a standard compact laminate HPL panel behaves very differently under stress than the thin sheets bonded to particleboard you see in cheaper installs. That difference in…
