Steel Structure Connection System

Product Overview

Steel Structure Connection System is a complete range of structural steel connection components designed to connect, secure, and reinforce steel members in construction and engineering projects. A complete system may include high strength bolts, anchor bolts, steel connection plates, base plates, gusset plates, splice plates, nuts, washers, and other structural steel connection accessories.

The connection system plays a critical role in transferring loads between structural members and creating stable steel frames. It is widely used for steel beam-to-column connections, column base connections, beam splices, column splices, bracing connections, truss connections, and other structural steel joints.

ZSJH Steel Structure provides customized steel connection components manufactured according to engineering drawings, CAD files, BOMs, connection details, technical specifications, and applicable project standards.

Product Types

Our Steel Structure Connection System can be configured with different components according to the structural design and connection requirements.

Available configurations can include:

• Structural Hex Bolts

• Heavy Hex Structural Bolts

• High Tensile Bolts

• Bolt Assemblies

• Matching Structural Nuts & Washers

2. Anchor Bolts

Anchor bolts are used to connect steel columns and base plates to concrete foundations.

Common configurations include:

• L-Type Anchor Bolts

• Custom Connection Plates

4. Base Plates

Steel base plates are installed beneath steel columns and work together with anchor bolts to transfer structural loads to concrete foundations.

5. Nuts & Washers

Matching nuts and washers can be supplied with structural bolts to form complete bolt assemblies for steel structure installation.

Product Specifications

Materials & Strength Grades

Steel connection components can be manufactured from suitable carbon steel, structural steel, or alloy steel according to project specifications.

Common structural steel grades may include:

• ASTM A36

• ASTM A572

• S235JR

• S275JR

• S355JR

• S355J2

• Q235B

• Q355B

Structural bolts can be supplied in strength grades such as 8.8 and 10.9, where applicable to the specified standard and project requirements.

Material grades, mechanical properties, bolt grades, and applicable standards are confirmed according to the customer's engineering requirements before production.

Dimensions & Custom Specifications

One of the key advantages of our Steel Structure Connection System is its project-specific customization capability.

We can manufacture components according to:

• Bolt Diameter

• Bolt Length

• Plate Length

• Plate Width

• Plate Thickness

• Bolt Hole Diameter

• Hole Quantity

• Hole Spacing

• Hole Position

• Edge Distance

• Slot Dimensions

• Connection Configuration

• Component Quantity

For non-standard steel connection components, customers can provide CAD drawings, PDF drawings, shop drawings, BOMs, or detailed specifications for production.

Connection Methods

Bolted Steel Connection

Bolted connections use high strength bolts, nuts, washers, and connection plates to connect structural steel members.

Common applications include:

Beam-to-Column Connections, Beam Splices, Column Splices, Bracing Connections, Truss Connections, and Structural Frame Connections.

Welded Steel Connection

Connection plates, base plates, and other fabricated steel components can also be manufactured for welded structural connections according to engineering drawings and welding specifications.

Column Base Connection

A typical column base connection may include:

Steel Column + Base Plate + Anchor Bolts + Nuts + Washers + Concrete Foundation

This connection transfers loads from the steel column into the foundation.

Precision Fabrication

Accurate fabrication is essential for steel connection components because incorrect dimensions or bolt-hole positioning can create difficulties during steel structure erection and installation.

Our fabrication capabilities include:

• CNC Plasma Cutting

• CNC Laser Cutting

• CNC Drilling

• Hole Punching

• Plate Cutting

• Slot Cutting

• Welding

• Grinding

• Shot Blasting

• Primer Coating

• Protective Painting

• Hot-Dip Galvanizing

Fabrication parameters can be controlled according to the approved engineering drawings and project specifications.

Surface Treatment

Different surface treatment options can be supplied depending on the project environment and corrosion protection requirements.

Plain / Black Finish

Suitable for applications where additional corrosion protection is not required or where further coating will be applied.

Primer Coating

Provides basic corrosion protection and can be used as part of a multi-layer structural steel coating system.

Protective Painting

Coating systems, colors, and paint specifications can be customized according to project requirements.

Hot-Dip Galvanizing

Provides enhanced corrosion resistance and is suitable for outdoor, humid, or exposed steel structures.

Applications

Steel Structure Connection Systems are widely used in:

Steel Structure Buildings

For connecting primary and secondary structural steel members.

Steel Warehouses

Used in beam-to-column connections, bracing systems, column bases, and roof structures.

Industrial Workshops
