Explore how subway station facilities are fabricated from sheet metal for underground transit. Learn about fire safety, material selection, and real-world installations.
Where Subway Facility Fabrication Fits in a Build
Subway stations require specialized facilities that withstand underground environmental conditions, high passenger traffic, and stringent fire safety requirements. Metal fabrication provides the durability, fire resistance, and design flexibility needed for underground transit infrastructure. At Fulei Metal, we fabricate subway facility components for transit authorities across Europe and Southeast Asia.
Subway Facility Types
Platform screen doors provide safety barriers between platforms and tracks. Station furniture includes seating, information displays, and waste receptacles. Tunnel ventilation facility housings protect ventilation equipment. Emergency exit facility housings protect emergency stairwell equipment. Station entrance canopies provide weather protection at street level. Signage and wayfinding structures guide passengers through complex stations.
Choosing Material for Subway Facility Fabrication
Stainless steel (grade 304 or 316L) is the standard material for subway facilities, providing fire resistance, corrosion resistance, and durability for underground environments. We use 1.5 to 3.0 mm sheet and tube. Fire-rated materials may be required for certain applications per underground transit fire safety standards. Powder coating provides color options for station identity and wayfinding. All materials must meet underground transit fire safety standards including smoke generation and toxicity limits.
Design Choices That Affect Subway Facility Fabrication
Subway facilities must withstand continuous high passenger traffic and potential vandalism. All materials must meet stringent fire safety standards for underground applications. Facilities must be designed for easy cleaning and maintenance in underground environments. Accessibility must be maintained for wheelchair users and passengers with disabilities. Emergency egress must not be impeded by facility placement. All edges must be smooth for passenger safety. Aesthetic design should create a pleasant underground environment that complements station architecture. Facilities must be designed for efficient installation during limited maintenance windows.
Cutting, Bending and Welding Subway Facility Fabrication
Our TRUMPF fiber laser cuts facility components, frame parts, and mounting plates from flat sheet stock. CNC press brake machines form panels, frame profiles, and support brackets. Tube processing equipment cuts and notches frame tubes. Component assembly uses TIG welding for stainless steel, producing smooth, fire-safe structures. Surface treatments include electropolishing, powder coating with fire-rated formulations, and anti-graffiti coatings.
Field Notes: Subway and Underground Station Fittings
Station fittings below ground are specified around a set of conditions that rarely apply together elsewhere: a humid atmosphere that never fully dries, constant use, a cleaning regime that includes aggressive products, and a strict requirement that nothing in the public areas can be climbed on or used as a foothold. For metal parts that means the corrosion environment has to be taken seriously even though the parts are indoors – a galvanized or stainless specification rather than a powder coat over bare steel, because the coating will be damaged during installation and there is no second chance to protect the steel underneath. It also means every fixing is either concealed or made tamper-resistant, every cut end and open tube is closed, and the assembly is checked for stability under a load applied at the edge of a horizontal surface rather than at its centre.
How We Quote Subway Facility Fabrication
Subway facility fabrication requires fire safety compliance, underground durability, and transit-grade manufacturing. Fulei Metal’s capabilities make us a trusted partner for underground transit infrastructure projects.
If you are sourcing this type of part, our DFM engineering review page covers the tolerances, batch sizes and inspection we work to, and custom sheet metal fabrication shows the wider range we produce in Ningbo, China.

Fire and Smoke Requirements in Transit Fit-Out
Metal components for a metro or rail environment are specified against fire performance rules that vary by network and by country. What does not vary is the principle: the material has to meet the reaction-to-fire and smoke-toxicity class the project specifies, and that has to be evidenced by a test report from an accredited laboratory for the product actually being installed. We fabricate the metal parts to the material and the construction on the drawing. The fire classification and its certification belong to the system supplier or the project’s own approvals process, and we do not substitute that step.
- Send the specified material grade and any coating restriction with the enquiry; coatings can change the smoke classification.
- Tell us which network or authority the parts are going into, so we know what documentation the project will ask for.
- Where a drawing names a standard, we work to it and we say so on the quote rather than assuming an equivalent.
Details That Survive a Transit Environment
Public transit equipment is used hard and cleaned harder. Fixings get tampered with, panels get pried at, and every exposed edge in a passenger area is a safety and a liability question. We use tamper-resistant fasteners where the drawing asks, keep panel gaps tight enough that a coin or a tool will not enter, and radius every edge a passenger can contact. Cable entries get grommets so the harness is not cut by the hole it passes through.
Cleaning regime matters to the finish. If the parts will be wiped down with a strong agent, powder coat specification and stainless grade both change, so tell us what the cleaning process is. Lead time is quoted after drawing review and process confirmation, and transit projects generally benefit from a first-article inspection before the production run.

Most enquiries that start on a page like this are not an order for Subway Facility Fabrication — they are a search for a factory that can make something like it. Send us your drawing, 3D model or sample and we will review the manufacturing process and the quotation requirements, then come back with a process plan, a price and a lead time.
We work from 2D drawings, STEP / DWG / DXF / PDF files, or a physical sample if that is all you have.

Trade Terms and Delivery
We quote under the standard Incoterms your logistics team already works with, and build the packing and documentation around the one you choose.
- EXW — you collect from our Ningbo facility and run export clearance through your own forwarder.
- FOB Ningbo — we deliver to the vessel at Ningbo port and handle export clearance.
- CIF — we cover carriage and insurance to your named destination port.
- DDP — we handle carriage, insurance, import clearance and duties through to your door.
Send your destination country, target delivery date and preferred trade term together with the drawing. Request a quotation.
Payment Terms
How a project is paid for is agreed before production starts, and the structure that applies to your order is stated on the quotation and on the order confirmation, so there is no ambiguity later.
- 30% advance payment with the order and the 70% balance before shipment — our standard structure.
- 70% advance payment with the order and the 30% balance before shipment — used for some projects.
- 100% payment in advance before production starts — used for some projects.
If your finance team works to a fixed structure, say so in the first enquiry and we will confirm what applies to your order before you commit. Request a quotation.
Quotation Time
We quote from your drawings. How long that takes depends on what the part asks for:
- Simple parts — quoted within 24 hours. Laser-cut blanks and bent components, supplied with complete 2D or 3D drawings. Mon–Fri, GMT+8.
- Complex assemblies — quoted after the drawing review. Payment kiosks, multi-part welded frames, enclosures with purchased hardware, or anything needing a coating or assembly trial. We confirm a quotation date once the scope is clear.
Production lead time is quoted separately, after drawing review and process confirmation. Send your drawings.
