90degree fixed pipe connector Function: joins two steel pipes at a right angle to form a rigid 90degree joint, enabling stable corner connections for frames and structures. Materials and finish: made from steel; anticorrosion and rustproof for durable use. features smooth surfaces and polished edges for safe handling and a clean appearance. Installation: easy and convenient to install and use; designed for practical, reliable assembly. Compatibility and performance: suitable for steel pipe systems in a variety of applications; built to provide durable support in common pipebased constructions. Applications: widely used in shelving, farm buildings, greenhouses, pig pens, sheep and cattle sheds, purlin supports, scaffolds, roofs and fences, and other pipebased projects. Use scenarios: 1) Shelving frame: connect vertical and horizontal members at 90 degrees to create strong corner joints. 2) Greenhouse rack system: assemble frame corners for stable benches and supports. 3) Barn or shed construction: form rightangle joints for roof supports, wall frames, or fencing structures.
