Project Delivery Framework

Five Controlled Stages from Design to Site.

One coordinated workflow keeps the approved design, supplied scope and site information aligned.

Design Basis

Building use, dimensions, site loads and required design codes are confirmed first.

Scope Confirmation

The steel frame, envelope, accessories and project documents are defined as one package.

Production Control

Fabrication and surface treatment follow approved drawings and inspection stages.

Packing & Loading

Marked components are bundled and loaded against the project packing list.

Installation Support

Erection drawings and technical guidance support the local construction team.

Engineering & Detailing

Engineering Ready for Fabrication and Site Assembly.

The engineering workflow turns the project brief into coordinated structural and fabrication information. Building use, span, height, openings, equipment, environmental loads and destination requirements are reviewed before the final system is released.

Preliminary layout and 3D scheme Structural analysis and calculation report General arrangement and connection design Fabrication drawings and bill of materials Foundation reaction information Erection drawings and installation documents

Project-specific engineeringFinal member sizes and connections follow confirmed site data, loads, codes and scope.

Inside the Manufacturing Base

Steel Fabrication from Cutting to Final Inspection.

The manufacturing base brings material preparation, structural fabrication, surface treatment, inspection and packing together in one controlled environment.

**Main Fabrication Workshop**Dedicated production areas connect steel preparation, fabrication and material movement.

**CNC Plate Cutting**Plates are nested and cut against coordinated fabrication information.

**Structural Welding**Primary members move through controlled fit-up and welding stations.

**Component Fit-Up**Connection plates and member geometry are checked before finishing.

**Packing Preparation**Finished members are marked and grouped for the project shipment.

Quality & Traceability

Inspection and Traceability at Every Stage.

Inspection begins with incoming steel and continues through fabrication, surface treatment, member identification and final shipment release.

Incoming Materials

Steel grade, dimensions and available mill documentation are checked before release to production.

In-Process Control

Cut dimensions, hole positions, assembly geometry and welding are reviewed at defined stages.

Surface Protection

Preparation and coating are controlled against the confirmed project specification.

Final Release

Member marks, quantities, finish and packing information are checked before loading.

Steel component dimensional quality inspection

Project Quality DossierMaterial documents, inspection records, coating records and packing information.

Certification documents available for project review

Complete Building Supply

The Complete Steel Building Package.

Steel products and building-envelope materials are coordinated around the same approved building scope, reducing interfaces between separate suppliers.

Primary Structure

Columns and rafters Trusses and crane beams Connection plates and base plates

Secondary Steel

C/Z purlins and girts Bracing and tie members High-strength bolts and anchors

Building Envelope

Roof and wall sheets Insulated sandwich panels Flashing, gutters and downpipes

Project Options

Doors, windows and skylights Ventilation and daylighting Crane and mezzanine coordination

Marked steel components prepared for export loading

Export Logistics & Site Support

Packed for Export. Documented for Site.

Export delivery connects production records with member marks, packing lists, container planning and the information needed by the receiving site team.

Member Identification

Piece marks correspond with drawings and packing information.

Export Packing

Components are grouped and protected for ocean transit.

Loading & Documents

Container planning and export paperwork are coordinated together.

Arrival Support

The local team receives erection information and technical support.

Company FAQ

Before Your Project Starts.

Confirm the design basis, supply scope, inspection plan and support responsibilities before production begins.

Are you a steel structure manufacturer or a trading company?+

ZONBUILT coordinates engineering, steel fabrication, building-envelope supply, export delivery and installation support through its manufacturing and project teams.

Can you design for standards outside China?+

The design basis can be developed around the project location, local loading conditions and the required target-market standard. The exact code, approval responsibility and document scope are confirmed before engineering begins.

Can a client or third party inspect production?+

Factory visits and project-specific inspection arrangements can be coordinated. Hold points, document requirements and the responsible inspection party should be agreed before production.

What support is available after the shipment arrives?+

The project package can include erection drawings, installation manuals, remote technical assistance and optional engineer guidance, depending on the confirmed contract scope.
