Alu Design & Services shakes up marine seating market, launching improved Alutech 400 and 500 products at reduced costs. Alu Design & Services (Alu Design), a world leader in the innovative design and manufacture of advanced pilot chairs and deck rails, is re-launching two of its core product offerings with enhanced design and production standards. The result is an even better seating experience at costs of up to 20% less than previous models. From today, the Alutech 400 and Alutech 500 are available in aluminum made from pressurized die-casting. This production technique greatly reduces the product weight, makes the 400 and 500 even more robust than their predecessors and, crucially, allows Alu to offer the chairs with a reduced price tag.
