Steel Grating Built To The Opening You Actually Have
ShengJingYe produces heel guard, concrete cover, ditch, welded and press locked steel grating and ball joint handrail in carbon steel, stainless steel and aluminium alloy, from an 8000 square metre workshop in Yantai.
Small Batch And Customized Production Is The Business Not The Exception
The export company was set up in 2023 specifically to handle the variety that foreign buyers ask for: panel sizes, hook details, bar pitch and surface treatment set against your drawing rather than against a stock list.
Welded Press Locked And Fabricated Under One Roof
Pressure welding, press locking, stamping, laser cutting, framing and surface treatment happen in the same 8000 square metre workshop, which is why a panel and its frame and its handrail arrive together and in the same finish.
The Coating Decides How Many Winters A Panel Survives
Hot-dip galvanizing, electroplated galvanizing, painting and acid passivation are all produced here, so the surface treatment is chosen against the environment the panel will live in rather than against the invoice.
Six Families Of Steel Grating From One Yantai Workshop
Steel grating and the steelwork that goes with it: heel guard grating with the slot closed down so heels and castors cannot drop through, concrete cover panels with hooks for chambers and trenches, ditch grating for drainage runs, pressure welded panels for platforms and walkways, press locked panels where the top has to be flush, and ball joint stanchions and handrail to protect the edge of all of it.
Heel Guard Grating
Narrow-slot grating for places where people walk in heels, wheels or walking aids.

See the specificationFive Kinds Of Buyer With Five Different Failure Modes
Overseas fabricators, drainage channel manufacturers, civil and industrial contractors and plant maintenance teams. The export company exists because those buyers need panel sizes and details that a domestic stock list does not carry, in quantities that are project-sized rather than container-sized.
Food And Beverage Processing
Floors that are washed down every shift, drainage that is inspected, and grating that has to come up by hand for cleaning.
See what they specifyDrainage And Water Management
Channel systems, gullies and chambers where the steel top has to suit an opening that was cast rather than machined.
See what they specifyIndustrial Plant And Processing
Platforms, walkways and trench covers inside working plants, where the grating and its handrail should arrive as one package.
See what they specifyCommercial Buildings And Public Space
Entrances, forecourts and concourses where the grating is walked on by the public and looked at by everyone.
See what they specifyMarine And Coastal Projects
Chloride, spray and constant damp, where a zinc coating has a much shorter life than the structure it is protecting.
See what they specifySteel Grating Fails At The Edges Not In The Middle Of The Mesh
Grating fails at the edges and the joints, not in the middle of the mesh. Panels arrive out of square and will not line up. Hooks welded on after galvanizing rust off. Site-cut ends go bare. Covers rock in frames that were cast, not machined. Everything here is drawn first, fabricated complete, and coated last, so the parts that normally fail are the parts that are protected.
What Usually Goes Wrong
- Panels galvanized before fabrication, so every cut end and hook weld is bare steel
- Covers ordered to a nominal opening that will not drop into the opening as cast
- Stainless panels welded and then shipped without acid passivation
- A section chosen on price per square metre rather than on span and deflection
- Grating and its handrail bought separately and arriving weeks apart
What This Factory Does Instead
- The head office has been making steel grating since 2010 and the export company since 2023. Production is one automatic pressure welding line plus more than thirty stamping, welding and laser cutting machines in an 8000 square metre workshop, with a design team that produces a 3D model of the panel and its frame before any bar is cut. Load classes, certifications and lead times are confirmed in writing per order rather than published as marketing numbers.
- A 3D model of the panel, its frame and the opening before any bar is cut
- Hooks, banding and cut-outs fabricated before coating, never after
- Panels checked for size, squareness and bar pitch before they are banded
Eight Stages From A Measured Opening To A Coated Marked Panel
These are the stages a panel goes through in the Yantai workshop, and the specific failure each one exists to prevent.
Drawing And 3D Model
A grating that is wrong on paper is wrong in steel, and steel is expensive to be wrong in.
The design team models the panel, the frame and the opening it has to sit in before any bar is cut, so bearing bar pitch, panel division and frame clearance are agreed in a drawing rather than discovered on site.
Material Selection
Carbon steel and stainless steel fail in completely different places.
Carbon steel with a hot-dip galvanized coat for general traffic and drainage, stainless steel with acid passivation where washdown, chloride or food-grade cleaning is involved. Aluminium alloy is produced where weight is the constraint.
Cutting And Stamping
Bar ends that are not square never sit flat in a frame.
Bearing bar and cross bar stock is cut and stamped on the plant’s laser cutting and stamping equipment, which is also what makes serrated and toothed edges repeatable across a batch.
Pressure Welding Or Press Locking
The joint between bearing bar and cross bar is the whole strength of a panel.
Welded panels are produced on the automatic pressure welding line. Press locked panels are assembled by forcing the cross bar into the bearing bar under pressure, which is what gives a flush top surface without a weld bead.
Framing And Fabrication
Most grating complaints are about edges, not about the mesh.
Banding bar, end plates, hooks, hinges, lifting handles and cut-outs for pipework are fabricated to the drawing, so the panel arrives as a finished cover rather than as a sheet to be trimmed on site.
Surface Treatment
The coating decides how many winters a panel survives.
Hot-dip galvanizing, electroplated galvanizing, painting or acid passivation, chosen against the environment the panel will live in rather than against the invoice.
Inspection Before Packing
A panel that does not drop into its frame is scrap once it is in a container.
Panels are checked against the drawing for size, squareness, bar pitch and coating finish before they are banded and stacked.
Packing And Export
Grating is heavy, sharp and easy to damage in transit.
Panels are stacked flat, banded and packed for sea freight, which is the route most of this plant’s output takes.
