Made with an anodised aluminium frame. 45 x 35 mm extruded section for the arches, meaning the tarp sections between each arch can be replaced separately by the client. This avoids sending the whole tunnel to the factory should any of the panels rip. Horizontal reinforcements make the tunnel stable. Set of assembly pins in AISI 304 stainless steel. 50 x 13,5 mm extruded aluminium scissor opening. The rotating heads are in die-cast aluminium alloy. 4 extra torquing points to attach and stretch the canvas (only one of its kind) Sliding runners for the scissors in POLYZENE 500, reducing friction by 60%, minimising tunnel extension and retraction work. Covering tarp in high tenacity polyester; finished in PVC on both sides. Flame-retardant M-2 (620 g). Nylon wheel: Default (for great use). Optimum sliding on parquet, linoleum and smooth surfaces. Rubber wheel: Similar usage to the nylon wheel. Better grip due to the rubber finish. Pneumatic wheel: For outdoor use (on grass and gravel/earth). Consult us for measurement-based prices.
