Advanced Shop Drawing & Value Engineering
Transforming conceptual designs into precise, buildable blueprints. We optimize structures and materials to reduce project costs and risks without compromising your architectural vision.
1:1 Mock-Up & Prototyping
Physical samples and full-scale mock-ups help review appearance, dimensions and assembly details against approved project references before production.
Expert Engineering Liaison & Project Delivery
Ensuring seamless project execution from conceptualization to handover. Our dedicated engineering and technical teams collaborate directly with architects and main contractors, providing proactive technical support, design optimization, and streamlined coordination to keep your project on schedule.
Each gate closes a specific project risk: incomplete inputs, unresolved interfaces, undefined appearance, uncontrolled revisions or loss of panel identity during delivery.
Log the latest drawings, BOQ, application, quantity, project location, required date and finish reference. Drawing revisions and missing decisions are recorded before detailing starts.
Issued input register with revision status and open technical queries
Check panelisation, joint positions, folded returns, access, backing, fixing zones and interfaces with stone, glass, timber, ceilings and MEP services.
Marked-up drawings showing interfaces, unresolved dimensions and proposed construction logic
Record grade, nominal thickness, initial mill surface, final grain or texture, PVD colour, viewing direction, protective treatment and physical approval reference.
One controlled schedule linking each panel type to its material and finish reference
Dimension datums, overall size, openings, bend lines, radii, weld locations, reinforcement, hardware and panel IDs are frozen in an approved revision.
Approved fabrication drawings with panel numbering and revision control
Evaluate colour, gloss, grain direction, texture scale, corner treatment and welded restoration under representative lighting. Screen images are not used as final acceptance references.
Signed finish sample, detail sample or 1:1 mock-up retained as the production master
Sequence cutting, forming, joining, dressing, polishing or texturing, PVD and protection. The first completed unit is compared with drawings and the approved physical reference.
First-article acceptance plus defined in-process checks for repeat production
Verify critical dimensions, visible finish, quantity, panel ID and assembly relationship before applying film, edge protection, wrapping and crate identification.
Inspection status, panel schedule, packing list and crate-to-area identification
GRADE & TRACEABILITY
Define SUS 304, 316 or 316L, nominal thickness, sheet condition and initial surface such as 2B or BA. Where required, heat or batch identity is linked to the supplied material certificate.
Grade selection follows exposure and fabrication needs; a decorative coating cannot compensate for an unsuitable base grade.
CUTTING & DATUMS
Laser-cut profiles, notches, holes and service openings are referenced to agreed datums. Burrs, sharp edges, visible cut faces and heat-affected marks are addressed before forming or finishing.
Critical dimensions need a stated datum, tolerance and inspection method—not an assumed general tolerance.
BENDING & ROLLING
Bend radius, grain direction, springback, bend relief and tooling contact are reviewed before folding or rolling. Embossed and water-ripple sheets also require defined texture depth, untextured borders and usable panel area.
Deep texture, tight radii and reflective finishes require a trial piece because forming can distort pattern, flatness and reflection.
WELDING ROUTE
Joint type, weld position, compatible filler, sequence, restraint and access for dressing are set before welding. Heat tint, distortion and contamination are treated according to the material and final surface requirement.
A weld that is structurally acceptable may still fail an architectural finish if distortion or grinding remains visible under project lighting.
SURFACE RESTORATION
Coarse weld removal is followed by progressively finer grinding or polishing. Hairline direction, satin uniformity and mirror clarity are compared with the production master rather than judged by abrasive grit alone.
Published Ra ranges are guidance only: No.4 is commonly reported around 0.18–0.64 μm and No.8 around 0.02–0.10 μm; the approved sample remains the visual acceptance basis.
PVD DEPOSITION
PVD is a thin vacuum-deposited coating, not a levelling layer. Mirror, hairline, satin and blasted substrates produce different reflection and colour depth even when the nominal PVD colour is the same.
Complete major cutting, forming, welding and restoration first; later grinding removes the coating and deep deformation may crack it.
PANEL SYSTEM
Panel size, returns, rear stiffeners, weld studs, adhesive points, subframe support and fixing sequence all affect oil-canning and reflected-image distortion.
Mirror and large-format panels require an agreed viewing distance, lighting condition and mock-up because local waviness becomes visually amplified.
EXPOSURE & CLEANING
Humidity, airborne chlorides, sheltered deposits, drainage, touch frequency and cleaning access are considered together. Coarser finishes retain more contamination than smooth, clean-cut surfaces.
Coastal or exterior use needs project-specific review of grade, surface, joints and maintenance; PVD alone does not create marine-grade performance.
Acceptance is tied to measurable dimensions, named physical references and identifiable production records—not to broad claims of premium quality.
Material grade, nominal thickness, surface condition, flatness, scratches and protective film are checked against the purchase and project requirements.
MTC or supplier certificate is cross-referenced to the received batch when traceability is specified.
Overall size, diagonals, hole positions, folds, radii, curvature and interface dimensions are checked from drawing datums with suitable gauges, templates or measuring tools.
Results are recorded against drawing-specific tolerances; no unstated universal tolerance is implied.
Visible-face distortion, weld location, penetration requirement, spatter, heat tint, dressing marks and restored grain are reviewed after joining.
Welding procedure, filler and inspection level are defined by the joint function and agreed project requirement.
Panels are checked for grain direction, gloss continuity, texture density, colour variation, waviness, dents and scratches under an agreed viewing condition.
The coded physical production master takes precedence over photographs or monitor colour.
The sample records substrate grade, base finish, colour direction, gloss or texture, coating sequence and intended application.
A unique sample code and approval status prevent an untraceable colour name from becoming the production standard.
A representative bend, return, corner or welded junction confirms tooling marks, edge appearance, grain recovery and coating compatibility.
This sample exposes risks that a flat colour coupon cannot show.
Full-scale panel size, joint width, reflected-image behaviour, fixing method, adjacent materials and representative lighting are reviewed together.
Comments are closed against a dated mock-up revision before repeat production.
Each panel or assembly is linked to its drawing ID and installation area. Film compatibility, edge protection, wrapping, crate support and unpacking sequence are checked.
The packing list and crate map preserve panel identity from factory inspection to site distribution.

Early answers help align design intent, approvals, production and delivery.
Provide the application, project location, drawings or BOQ, material and finish direction, quantity and required delivery date. Xinmao identifies missing information and confirms the review scope before production planning.
Yes. Concept information can be reviewed for material selection, panelisation, joints, edges, reinforcement and fabrication feasibility. Production begins only after the necessary dimensions and technical information have been coordinated and approved.
The physical reference should be approved before the related production finish is released. Review colour, gloss, grain direction, texture, viewing angle and representative project lighting rather than relying on screen images alone.
Major cutting, forming, welding and surface restoration should normally be coordinated before PVD. The coating does not hide substrate defects, and later grinding, welding or deep deformation can damage the finished layer.
Directional finishes should be marked in drawings, samples and panel identification. Production and packing references help preserve the intended orientation through fabrication and installation.
Review material grade, chloride exposure, surface roughness, drainage, joints, cleaning access and maintenance together. PVD colour alone does not increase the corrosion resistance of an unsuitable base material.
Depending on the agreed project scope, documents may include approved drawings, material records, finish references, dimensional checks, inspection records, panel identification and packing lists. Required documentation should be defined before production.
Protection is coordinated around the finish, geometry and delivery route. Measures can include protective film, edge and corner protection, individual wrapping, panel numbering and project-specific export packing.
