Building expansion joint rubber strips are key sealing elements for construction structures, installed in expansion joints gaps designed to absorb structural movement from temperature changes, settlement, or seismic activity. Their primary role is to seal these joints, preventing water, dust, and debris infiltration while accommodating structural expansion and contraction. Made of elastic, weather-resistant materials like EPDM or neoprene, they protect internal structures from damage and maintain thermal insulation. Widely used in bridges, high rises, industrial plants, and roads, they are critical for structural durability and safety.
