Custom Steel Construction and Fabrication for Heavy-Duty Industrial Applications
HALDEN provides custom steel construction and fabrication services for customers who need drawing-based steel components, welded assemblies, hoppers, chutes, brackets, mounting plates, structural frames, and engineered-to-order machine elements. We manufacture according to your drawings, tolerances, specifications, site limitations, fixing requirements, and inspection level.
Custom Steel Fabrication Is Not Just Welding Steel Together — It Is Controlling Fit-Up, Tolerances, Material Traceability, Inspection, and Site Installation Risk.
HALDEN manufactures steel components according to your drawings, application limits, fixing method, inspection level, and documentation requirements.
Steel Tailoring for Industrial Projects
HALDEN positions custom fabrication as “steel tailoring”: components are tailor-made to fit your application, site limitations, fixing requirements, and engineering drawings. For customers who already have drawings, HALDEN follows the drawings and controls tolerance, specifications, quality checks, and documentation during fabrication.
Made to Drawing
We manufacture according to PDF, DWG, DXF, STEP, or customer sketches, while checking tolerances, manufacturability, and fit-up requirements.
Prototype to Batch Production
HALDEN can support one-off prototypes, trial parts, repeat production, spare parts, site-fitted steelwork, and engineered-to-order components.
Controlled Quality and Documentation
Material certificates, welding control records, dimensional inspection, final checks, photo documentation, NDT, and third-party inspection can be arranged according to project requirements.

| Surface Preparation | Blasting, priming, painting, and project-specific coating on request. | Outdoor steel structures, corrosion protection, transport protection, and project specification compliance. |
Materials and Steel Grades
HALDEN processes boiler steels, carbon steels, stainless steels, and other grades according to project drawings, working conditions, corrosion requirements, pressure or temperature environment, and applicable EN / ASTM / JIS standards.
Carbon Steels
Suitable for general welded structures, frames, brackets, hoppers, chutes, base plates, machine supports, and industrial steelwork.
Boiler Steels
Used for pressure, boiler, thermal, high-temperature, and process equipment related fabrication where project standards require specific steel grades.
Stainless Steels
Used for corrosion-resistant applications, chemical process equipment, sanitary-related structures, and stainless custom fabrications.
If your project requires EN, ASTM, JIS, GB, or another material standard, send the drawing and grade requirement. HALDEN will review availability, manufacturability, welding suitability, and inspection needs before quotation.
Custom Fabrication Workflow
A clear workflow helps reduce drawing errors, fabrication rework, inspection disputes, packing problems, and site installation delays.
Drawing Review
Review PDF, DWG, DXF, STEP, sketch, photos, tolerances, material grade, and project specifications.
Manufacturability Check
Check plate thickness, weld access, bending radius, hole positions, fit-up surfaces, and cost-saving opportunities.
Cutting and Forming
Cut, bend, roll, drill, tap, slot, and pre-machine parts according to approved drawings.
Welding and Assembly
Weld by suitable process, control fit-up, check distortion, and perform trial assembly where required.
Inspection and Documentation
Conduct dimensional checks, visual inspection, optional NDT, photo records, and MTC or project documents when required.
Surface Treatment and Packing
Blast, prime, paint, mark, protect, pack, and prepare for transport or site installation.
Quality Control and Documentation
HALDEN can prepare project-based documentation and inspection records according to customer requirements, including material certificates, welding procedure controls, dimensional inspection, final checks, photo documentation, NDT, and third-party inspection.
| Quality Item | What Can Be Provided | Why It Matters |
|---|---|---|
| Material Traceability | MTC material certificates on request. | Confirms steel grade, chemical composition, mechanical properties, and project compliance. |
| Welding Control | Project-controlled welding procedure controls and examination records. | Improves weld consistency and supports quality documentation for critical fabrications. |
| Dimensional Inspection | Dimensional checks and final checks before packing. | Reduces site fit-up problems, rework, and installation delays. |
| Photo Documentation | Optional fabrication process photos and packing photos. | Supports remote project management, customer approval, and shipment confirmation. |
| Inspection Level | Visual inspection, dimensional inspection, NDT, and third-party inspection if required. | Allows fabrication to match customer risk level, industry requirement, and project specification. |

|---|---|---|
| Plate Thickness | Suggest alternative thickness if it improves availability, cost, or fabrication efficiency. | May reduce raw material cost and lead time. |
| Joint Arrangement | Review weld access, joint type, fit-up sequence, and distortion control. | Improves welding quality and reduces rework risk. |
| Fabrication Sequence | Optimize cutting, forming, machining, welding, inspection, coating, and packing sequence. | Shortens production cycle and improves delivery reliability. |
| Installation Fit-Up | Add marking, trial assembly, reference holes, lifting points, or packing labels when needed. | Reduces installation confusion and site labor time. |
| Surface Treatment | Recommend blasting, priming, painting, or corrosion-resistant material based on environment. | Improves outdoor durability and project compliance. |
