Polyurethane (PU) has emerged as a modern alternative to Polyester resin in the climbing hold industry, favoured for its reduced weight and enhanced break resistance.

PU allows for greater creativity in hold design, particularly in the shaping of holds with more elongated and intricate tapers without the fear of chipping edges. While PU holds are less abrasion-resistant than their PE counterparts, their lightweight nature significantly facilitates easier handling and route setting, making them a popular choice for climbing gyms.

PU’s flexibility in design and practical benefits make it a compelling choice for modern climbing facilities and home walls alike.
