Custom Sheet Metal Structures Built Around Your Equipment.
Yishang manufactures drawing-based welded frames, equipment bases, cabinet structures, guards and integrated sheet metal assemblies for bulk OEM orders. We coordinate the fabricated skeleton, panels, interfaces, finish and packing as one production system so each batch arrives ready for the buyer’s equipment build.

Exported to 120+ countries
A Better Quote Begins by Confirming the Project Fits Our Factory.
We focus on custom metal products intended for wholesale, OEM programs and repeat purchasing—not raw sheet sales or one-off consumer jobs.
What We Manufacture
Welded equipment frames, fabricated bases, cabinet bodies, enclosure structures, guards, supports and integrated sheet metal assemblies.
What Your RFQ Should Include
Assembly drawing or sample, overall dimensions, material and thickness, interface datums, order quantity, finish and delivery destination.
Best Project Fit
Industrial and commercial equipment programs that need structural fit, repeatable batches, finishing, assembly, inspection and export packing.
Order Conditions
Custom products and established standard models are both welcome for B2B bulk production. We do not sell raw sheet, handle consumer repairs or take isolated one-off jobs.
Structural Problems Usually Surface During Assembly, Installation or Use.
A low fabrication price loses its value when a frame is out of square, mounting interfaces shift or a cabinet needs correction at the buyer’s assembly line.
The first frame fits, but later units start to shift.
Weld heat, bend sequence and inconsistent fixturing can change squareness, diagonals, flatness and the overall envelope across a batch.
We freeze the approved route and verify the structural datums and geometry that decide installation before production continues.
Panels pass alone, but the complete structure will not align.
Tolerance stack-up between the base, frame, doors, rails, panels and welded interfaces creates late drilling, shimming or fitting work.
We review connected interfaces and use fixtures, mating references or trial assembly where the equipment structure requires it.
Color, gloss, grain or weld cleanup changes between pieces.
Mixed appearance makes equipment look patched and can trigger customer complaints or full-batch sorting.
Visible faces, reference samples, masking points and acceptance limits are agreed before batch finishing.
Frames and cabinets arrive twisted, chipped or dented.
Large welded structures, protruding interfaces and cosmetic panels can move or take impact even when fabrication dimensions were correct.
Internal bracing, contact protection, lifting orientation and pallet support are matched to the completed structure.
From Main Frame to Finished Assembly, Built as One System.
Our main value is turning an assembly drawing into a repeatable fabricated structure. Panels, brackets, gussets and hardware are coordinated around the frame or enclosure instead of treated as unrelated items.
Welded Equipment Frames & Bases
Fabricated machine frames, equipment bases, support skeletons and welded subassemblies built around controlled datums and interfaces.
Cabinet & Enclosure Structures
Floor-standing cabinets, equipment bodies, enclosure skeletons, doors, internal rails and service-access structures.
Machine Guards & Access Structures
Protective guards, covers, access doors, ventilation structures and removable service sections for industrial equipment.
Structural Supports & Mounting Systems
Load-spreading supports, cross members, equipment mounts, gussets and reinforced connection areas integrated into the main fabrication.
Integrated Sheet Metal Assemblies
Frames and enclosure structures combined with panels, hinges, inserts, fasteners, seals and specified purchased hardware.
Coordinated Panels, Brackets & Gussets
Smaller fabricated items are supplied as matched elements of the larger structure, with their holes, bends and datums controlled around final assembly.
The Approved Structure Must Freeze Fit, Alignment and Finish.
Before volume production, the sample or first assembly should settle the structural points most likely to cause installation delay, field correction or acceptance disputes.
Overall Geometry
Envelope dimensions, flatness, squareness, diagonals, base points, frame datums and allowable weld distortion.
The structure reaches the buyer ready for positioning and installation instead of onsite straightening or shimming.
Equipment Interfaces
Mounting patterns, rails, openings, access zones, door gaps and relationships to the buyer’s mating equipment.
Equipment, panels and service features align across the completed fabrication.
Welded & Assembled Features
Joint locations, weld appearance, fixture references, fastener direction, hinge position, removable sections and assembly sequence.
Fabricated and purchased elements work together without late drilling, cutting or substitutions.
Finish & Delivery Protection
Color, gloss, weld cleanup, cosmetic faces, handling points, internal bracing, contact protection and pallet arrangement.
The approved structure remains aligned and presentable through transport, receiving and installation.
Choose Materials and Finishes Around the Product's Actual Job.
The best choice balances strength, corrosion exposure, appearance, fabrication route, order volume and total delivered cost.
Stainless Steel 304/316
For corrosion resistance, hygiene-sensitive equipment, visible housings and demanding service environments.
Mild & Galvanized Steel
For cost-controlled structures, cabinets, frames, guards and coated industrial products.
Aluminum
For lighter enclosure structures, panels and frames requiring corrosion resistance or an anodized appearance.
Red Copper & Brass
For selected conductive or decorative elements integrated into an assembly when the drawing requires them.
Protect
Powder coating, plating, passivation or other agreed corrosion-protection routes.
Control Appearance
Brushing, polishing, anodizing, color, gloss, texture, grain direction and weld cleanup.
Protect Functional Areas
Masking, grounding points, threads, mating faces, inserts and areas that must remain coating-free.
Material certificates, surface requirements and testing are confirmed according to the drawing, purchase specification and agreed project scope.
Send the Information That Defines the Structure, Interfaces and Batch.
Complete assembly inputs reduce assumptions and help us evaluate the fabrication route, fixturing, inspection and delivery plan for repeat production.
Assembly Drawing or Sample
2D drawings, 3D assembly, reference sample and the relationship between frames, panels and mating equipment.
Envelope & Interfaces
Overall dimensions, base points, mounting patterns, access zones, critical datums and allowable geometry limits.
Material & Thickness
Material grade, thickness, certificate needs and acceptable substitution rules.
Order Volume
Initial order quantity, repeat frequency and estimated annual demand.
Weld, Finish & Critical Controls
Joint requirements, surface finish, cosmetic faces, masking, key tolerances and inspection needs.
Delivery & Handling Plan
Required date, destination, lifting or handling constraints, bracing, packing, labeling and shipment preferences.
Questions B2B Buyers Usually Ask.
Do you accept one-piece or consumer orders?
No. Yishang focuses on wholesale, OEM, ODM and repeat-production metal projects. Sampling is supported as part of a potential bulk order.
Can you work from a sample if the drawing is incomplete?
Yes. We can review samples and available files, identify missing specifications and confirm what must be agreed before quoting or sampling.
Can you manufacture a frame together with its panels, doors and hardware?
Yes. The scope can combine the welded frame or enclosure structure with coordinated panels, access doors, hinges, inserts, fasteners, finishing, inspection and packing when defined in the RFQ.
How quickly will you respond?
We normally review submitted project information and respond within 12–24 hours. Complex assemblies may require questions before a reliable quotation can be prepared.
Send the Assembly Drawing. We Will Review the Structure as a Complete System.
Share the overall assembly, interface points, material, finish, order quantity and delivery plan. We will review project fit, fabrication route and the information needed for a responsible bulk-production quotation.
