Product Overview

Steel Connection Plate is a fabricated structural steel component used to connect and reinforce steel members in structural steel construction. It provides a reliable connection between steel beams, steel columns, braces, trusses, purlins, and other structural components through bolted or welded connections.

Our structural steel connection plates are manufactured according to engineering drawings, connection details, and project specifications. They can be precisely cut, drilled, punched, slotted, welded, and finished to meet the dimensional and installation requirements of different steel structure projects.

Steel Connection Plates are widely used in steel buildings, warehouses, industrial workshops, commercial buildings, bridges, steel frames, truss structures, and infrastructure projects.

Product Types

We provide different types of structural steel connection plates according to the connection design and application.

Gusset Plate

Used to connect bracing members, columns, beams, and truss components. Gusset plates are commonly used in braced frames and truss structures.

Splice Plate

Used to join two steel members together, such as beam-to-beam or column-to-column connections. Splice plates can be manufactured with precisely positioned bolt holes.

End Plate

Installed at the end of a steel beam or column and commonly used for bolted beam-to-column and beam-to-beam connections.

Cleat Plate

Used for connecting steel members at right angles or specific connection angles. It is commonly used in beam, purlin, and secondary steel connections.

Custom Steel Connection Plate

Custom connection plates can be manufactured according to CAD drawings, PDF drawings, connection details, BOMs, or customer-specified dimensions.

Material & Material Grades

Steel Connection Plates can be manufactured from structural carbon steel and other specified structural steel grades, depending on the engineering requirements of the project.

Common material specifications may include:

• ASTM A36

• ASTM A572

• S235JR

• S275JR

• S355JR / S355J2

• Q235B

• Q355B

Other material grades can be supplied according to customer specifications and applicable project standards. Material grade should always be confirmed according to the engineering drawings and project specification.

Dimensions & Specifications

Connection plates can be fully customized according to the required structural connection.

Precision Fabrication

Accurate fabrication is particularly important for steel connection plates because incorrect dimensions or bolt-hole positioning can affect field installation.

Our fabrication capabilities can include:

• CNC Plasma Cutting

• CNC Laser Cutting

• CNC Drilling

• Hole Punching

• Plate Cutting

• Slot Cutting

• Welding

• Grinding & Edge Treatment

• Shot Blasting

• Surface Painting

Bolt Hole & Connection Configuration

Steel Connection Plates can be supplied with customized bolt-hole arrangements based on the structural connection design.

Available configurations include:

• Round Bolt Holes

• Slotted Holes

• Multiple Bolt Hole Patterns

• Customized Hole Spacing

• Customized Hole Diameter

• Customized Edge Distance

• Welded Connection Details

Surface Treatment

Different surface treatment options are available according to the project environment and corrosion protection requirements.

Shot Blasting

Removes surface scale, rust, and contaminants and prepares the steel surface for subsequent coating.

Primer Coating

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

Protective Painting

Different coating systems can be specified according to the project environment and required corrosion protection level.

Hot-Dip Galvanizing

Provides durable corrosion protection and is suitable for outdoor or moisture-exposed steel structures.

Surface treatment, coating system, color, and thickness can be customized according to project requirements.

Applications

Steel Connection Plates are widely used in structural steel and construction projects, including:

• Steel Structure Buildings

• Steel Warehouses

• Industrial Workshops

• Commercial Buildings

• Steel Columns & Beams

• Steel Bracing Systems

• Roof Trusses

• Steel Frames

• Beam-to-Column Connections

• Beam-to-Beam Connections

• Column Splice Connections

• Steel Bridges

• Infrastructure Projects

• Prefabricated Steel Buildings

They are suitable for both bolted structural connections and welded steel connections, depending on the engineering design.
