1. New Product Release: Professional 4B Universal Mid Clamp for PV Racking System
Wuxi Jiancheng Cold Formed Steel Co., Ltd. officially launches the 4B Universal Mid Clamp for PV Racking System, a standardized fastener dedicated to photovoltaic support installation. This product fully meets the procurement demand of global solar engineering contractors for 4B Universal Mid Clamp for PV Racking, fixed-specification 40mm 4B Mid Clamp for Solar Mounting, and flexible Adjustable 4B Universal Clamp for Roof System. With high structural strength and wide compatibility, the clamp greatly simplifies on-site construction and strengthens the firmness of photovoltaic panel fixing, and has become a popular supporting accessory for distributed rooftop power stations and large ground photovoltaic projects.
2. Standard 40mm Size Design for General Solar Mounting
The classic 40mm specification is the mainstream size for most conventional photovoltaic panels, so our customized 40mm 4B Mid Clamp for Solar Mounting is precisely calibrated for 40mm frame photovoltaic modules. The clamping groove fits tightly with the panel border without extrusion damage or loose slipping. Made of high-strength aluminum alloy through precision cold forming, the clamp features strong compression resistance and anti-fatigue performance. It can resist long-term wind load, vibration and temperature difference changes outdoors, effectively avoiding hidden dangers such as panel displacement and loosening during long-term operation of power stations.
3. Adjustable Structure Adapts to Diverse Roof System Installation
Different fixed clamps can only match single panel thickness, which brings great trouble to mixed-type photovoltaic construction. Our independently developed Adjustable 4B Universal Clamp for Roof System realizes flexible fine adjustment of clamping range. It can adapt to multiple conventional thickness photovoltaic panels, applicable to color steel tile roofs, concrete flat roofs, slope roofs and other mainstream roof types. One kind of clamp can be used in multiple projects, reducing spare part types for construction teams and cutting overall project procurement costs.
4. Material Advantages & Outdoor Durability
All 4B universal mid clamps adopt aviation-grade aluminum alloy raw materials, with surface anodic oxidation anti-corrosion treatment. The finished products have excellent anti-rust, anti-oxidation and ultraviolet resistance, adapting to high-temperature coastal areas, cold plateau regions and dusty industrial areas. The integrated forming process eliminates assembly gaps, improves the overall bearing capacity, and effectively guarantees the long-term stable operation life of the PV racking system over 25 years.
5. Convenient Installation & Wide Application Scope
The 4B Universal Mid Clamp for PV Racking adopts a simple bolt locking structure, and construction workers can complete clamping and fixing quickly without special tools. It is widely used in household distributed photovoltaic rooftop projects, commercial factory rooftop power stations, ground large-scale photovoltaic power plants and agricultural complementary photovoltaic projects. Our factory provides unified standard finished products and drawing-based customized services to meet personalized demands of various special photovoltaic support projects.
6. Factory Strength & Contact Information
Wuxi Jiancheng Cold Formed Steel Co., Ltd focuses on the production of cold-formed steel profiles and solar mounting accessories, with mature automatic production lines and strict finished product inspection standards, and supplies stable photovoltaic fasteners for global solar installation companies and distributors.
