The Primary Steel Frame forms the core structural system of a steel building and provides the main support for the entire structure. It is generally made up of heavy steel columns, roof rafters, main beams, and rigid connection components.

The Space Frame Structure is an advanced three-dimensional steel structural system designed for buildings that require large spans, high structural stability, and flexible architectural forms.

Factory-fabricated heavy-duty steel staircases with anti-slip treads, landings and safety rails for warehouses, factories, mezzanines and equipment platforms.

Our Engineered Steel Platform is a prefabricated structural solution developed for equipment support, production operations, maintenance access and additional floor space.

Custom steel floor framing systems for factories, warehouses, equipment platforms and multi-level buildings. Engineering, fabrication and export supply from ZSJH Steel.

Our Portal Frame Structure is a cost-effective and highly adaptable steel framing system designed for warehouses, production plants, workshops, storage facilities, logistics buildings, and other large-span applications.

Our Secondary Steel Structure Components are designed to support the roof, wall, and bracing systems of prefabricated steel buildings. They work together with the primary steel frame to create a complete and stable structural system.

Our Primary Steel Frame is designed as the principal structural system for prefabricated and conventional steel buildings. It supports the major building loads through a combination of steel columns, rafters, beams, connection plates, and rigid joints.

Our Space Frame Structure is a three-dimensional steel structural system composed of interconnected steel tubes and high-strength nodes. Its stable geometric configuration provides excellent load distribution, high structural rigidity and efficient use of steel, making it ideal for buildings that require large column-free spaces.

A primary steel frame structure is the main load-bearing skeleton of a steel building system, consisting of steel columns, main beams, girders, and connection components. It transfers vertical loads, lateral loads, and building forces to the foundation, providing structural stability for industrial, commercial, and multi-story construction projects.

Our Secondary Steel Structure refers to a series of prefabricated steel components used to form, connect, and reinforce industrial building frameworks, including steel beams, steel columns, connection plates, angles, bracing members, and bolted connection assemblies. These components are widely used in factory buildings, warehouses, workshops, equipment platforms, mezzanine floors, and steel structure renovation projects.

Portal Frame Structure is a prefabricated steel building system consisting of steel columns, steel beams, rafters, bracing members, purlins, wall rails and connection components. It is widely used for industrial warehouses, workshops, factories, logistics centers, showrooms and agricultural buildings.
