ZSJH Steel produces made-to-order connection assemblies based on structural drawings, fabrication drawings or customer samples. Each component can be customized in material, plate thickness, dimensions, hole configuration, welding method and surface finish.

Our integrated fabrication service covers drawing review, material preparation, precision cutting, drilling, welding, surface protection, inspection, marking and export packaging.

Built for Efficient Steel Assembly

Steel connection parts must fit accurately at the project site. Incorrect hole positions, plate distortion or inconsistent dimensions can delay installation and increase adjustment costs.

Our production team carefully controls the key dimensions of each component, including:

• Overall length, width and height

• Plate thickness

• Hole diameter and spacing

• Welding position and weld size

• Contact-surface flatness

• Connection angle

• Component orientation

• Surface-coating thickness

Components are manufactured according to approved drawings to support faster alignment and more efficient on-site assembly.

Column Connection Components

Welded column bases, base plates, stiffened column shoes, column splice plates and customized connection assemblies for transmitting vertical and lateral loads.

Bracing Connection Parts

Gusset plates, clevis brackets, welded lugs and brace-end assemblies for roof bracing, wall bracing and structural stabilization systems.

Truss Connection Nodes

Fabricated connection nodes for tubular trusses, roof trusses, space frames and large-span steel structures.

Heavy-Duty Support Brackets

Welded corbels, equipment-support brackets, platform connectors and reinforced steel brackets for industrial applications.

Special OEM Components

Non-standard connection parts can be produced according to customer drawings, physical samples or specific project requirements.

Customization Capabilities

Product Features

Accurate Fabrication

CNC cutting and drilling help maintain consistent dimensions, clean plate profiles and accurate connection-hole positions.

Strong Welded Construction

Connection plates, stiffeners and structural sections are assembled using controlled welding procedures to provide stable load-transfer performance.

Reduced Installation Work

Accurately fabricated components reduce the need for on-site cutting, drilling, reworking and dimensional adjustment.

Flexible Component Design

We can manufacture small connection plates, medium-sized welded brackets and large heavy-duty structural assemblies.

Consistent Batch Production

Production templates, welding fixtures and inspection procedures help maintain consistency across large quantities of repeated components.

Project-Based Identification

Components can be marked and packaged according to building zones, installation sequences or drawing numbers, helping workers identify parts more efficiently.

Material Selection

The appropriate steel material depends on structural load, installation environment, welding requirements and project specifications.

Available materials include:

• General carbon structural steel

• Low-alloy structural steel

• High-strength structural steel

• Galvanized steel

• Stainless steel for special environments

• Customer-specified steel grades

Material certificates can be supplied for traceability and project documentation.

2. Material and production-process confirmation

3. Preparation of cutting and fabrication files

4. CNC cutting of plates and structural sections

5. Drilling, punching and edge preparation

6. Component positioning with fixtures

7. Welding and distortion control

8. Grinding and weld cleaning

9. Dimensional verification

10. Surface preparation and coating

Welding and Dimensional Control

Connection components are checked throughout the fabrication process to reduce deviations and ensure consistency.

Inspection items may include:

• Material grade and plate thickness

• Cut profile and edge condition

• Component dimensions

• Hole quantity, diameter and position

• Assembly angle and alignment

• Weld length and weld appearance

• Plate deformation and flatness

• Coating condition and thickness

• Product identification

• Packaging and loading condition

Magnetic-particle testing, ultrasonic testing or other non-destructive inspection methods can be arranged when required by the project.

FAQ

Can you review our drawings before providing a quotation?

Yes. Our technical team can review the component dimensions, material requirements, hole configurations, welding details and surface-treatment specifications before quotation.

Can you manufacture a component from a physical sample?

Yes. Components can be developed from drawings or physical samples. For complex parts, additional dimensional information may be required before production.

How can plate distortion be controlled during welding?

Appropriate welding sequences, positioning fixtures, balanced welding and dimensional correction are used according to the component design.

Can you perform a trial assembly?

Yes. Trial assembly or fit-up inspection can be arranged for components requiring accurate interfaces with beams, columns, braces or other structural members.

Can each component be marked with its drawing number?

Yes. Parts can be identified according to drawing numbers, building zones, assembly groups or installation sequences.

Are galvanized welded components available?

Yes. Components can be fabricated first and then hot-dip galvanized. Venting and drainage requirements will be considered during the drawing review.
