Since the industry’s early days, Allied’s Gatorshield® tubing has been the preferred choice for greenhouse and shade structures. No other tube can offer excellent tensile and yield strengths, combined with unsurpassed corrosion protection, and ease of formability. Gatorshield®’s triple layer of protection can be bent, cut, drilled, and swedged without worry of the galvanization peeling, flaking, or cracking. We offer a wide range of round and square tubing designed to meet the needs of greenhouse manufacturers such as Hoop Material, Purlins, Ground Stakes, and Bracing Supports.
