Fleet operators spend years chasing payload capacity. Shaving 200 kilograms off a trailer body translates directly to revenue — more cargo per run, less fuel burned, fewer cycles wasted at weigh stations. That math is why PP honeycomb panel applications have moved from niche aerospace components into mainstream truck and trailer manufacturing over the last…
Most commercial vehicle builders still spec plywood for trailer floors and van interiors. The upfront cost looks reasonable on any quote sheet. But plywood rots in humid and refrigerated environments — and it happens faster than most fleet managers want to admit. Aluminum corrodes under salt exposure. Both materials add dead weight that eats into…
A PP honeycomb core weighs roughly 1/32 of an equivalent volume of aluminum. That number alone explains why polypropylene honeycomb core applications have moved from niche boat interiors into truck bodies, RV walls, and refrigerated freight compartments. The shift is visible on our production floor. Rax Panel now outputs over 1,700 square meters of composite…
PP honeycomb core weighs roughly 1/32 of aluminum per unit volume. In an industry where every kilogram shaved off a truck body translates directly to payload capacity, that ratio matters. But most buyers evaluating lightweight truck and trailer panels stop at the weight spec and skip the harder question. How does this material hold up…
If you’re still quoting aluminum honeycomb to customers who need weight savings, you’re leaving money on the table. PP honeycomb panel uses have expanded well beyond basic packaging — the material now shows up in RV wall panel materials, refrigerated truck bodies, marine bulkheads, and architectural cladding. The polypropylene core weighs roughly 1/32 of an…
Every transportation manufacturer I talk to in 2026 has the same mandate: cut weight without sacrificing structural integrity. Polypropylene honeycomb core delivers on both counts. It weighs roughly 1/12 the mass of water and 1/32 that of aluminum per equivalent volume — yet maintains compressive and shear strength that holds up under actual load conditions.…
Ask any plant manager at a truck body or RV factory what drives their material spec sheet, and they’ll point to one line item: weight per square meter. PP honeycomb panel uses now range from caravan flooring to refrigerated truck walls to marine bulkheads — all because the core delivers 70% weight reduction versus plywood…
A proficient crew installs 600 square meters of sandwich panels in a single 8-hour shift. That speed is why commercial projects spec these systems. But sandwich panel installation only delivers real value when every joint seals tight and every fastener lands at the correct torque. One over-driven screw, one misaligned joint, or one skipped sealant…
