Metal Materials — Industries & Applications
Metal materials — steel, aluminium, copper, nickel and titanium in standard product forms — are an additional supply category for Zhongbo. They are sourced from confirmed mills, not produced in-house: for every item the mill identity, grade, dimensions and country of origin are confirmed before the order is accepted, and the mill documentation the project requires is provided. Zhongbo is the supply and documentation contact for these materials, not the mill.
This page sets out the industries that Zhongbo-supplied metal materials serve, and which forms and grades apply in each. For the full catalogue by metal group see the metal materials product hub; to request a quote use the metal materials RFQ checklist.
Across every industry below the model is the same: the buyer specifies the form, grade, dimensions and standard; Zhongbo identifies a confirmed mill, confirms grade and origin, and supplies with the certificate the project acceptance requires.
Challenges in metal materials
Fabricators and project buyers sourcing bought-in metal materials face recurring supply-side challenges:
- Material supplied without a confirmed mill, grade or origin — a provenance gap that EPC or owner specifications will reject.
- A grade given without a standard, or a standard without dimensions — neither is enough on its own to fix the material and price.
- Certificate type (EN 10204 3.1 vs 3.2) and any inspection not stated up front, changing the mill selection and the lead time.
- Multiple forms and metals for one project bought from separate suppliers, each with different documentation formats.
- Surface, finish or heat-treatment condition omitted, so the wrong material condition is sourced.
Construction & infrastructure
Construction and civil infrastructure projects need structural and functional metals in standard forms — plate, bar, tube and sections for frames, supports and civil works. Zhongbo supplies these to the stated grade and standard, with provenance and certificate confirmed per order.
- Steel — plate, bar, tube, angle and structural sections
- Aluminium — plate and profile
- Grade, dimensions and origin confirmed per order
Power, energy & grid
Grid construction, substation and renewable-energy work require structural steel, aluminium profile and copper for busbars and earthing. Materials are sourced to the EPC or owner specification, with the certificate and any inspection agreed before the order is placed.
- Steel — plate, bar, tube for towers, supports and substation work
- Aluminium — profiles and extrusions for trays and enclosures
- Copper — bar and strip for busbars and earthing
Manufacturing & fabrication
Fabricators and OEMs source steel, aluminium and copper stock in plate, bar, tube, strip, coil and profile to feed cutting, forming and machining. Zhongbo supplies to the stated form, grade and dimensions with the certificate the process requires.
- Steel, aluminium and copper in plate, sheet, bar, tube, strip, coil and profile
- Dimensions and tolerances confirmed per order
- Surface, finish or heat-treatment condition sourced to specification
Marine & shipbuilding
Marine and shipbuilding work uses plate and sections to marine grades and standards. Materials are sourced against the stated standard, with provenance and certificate — and any class-society or witnessed inspection — agreed at the enquiry stage.
- Steel — plate and sections to marine grade
- Corrosion-resistant grades where specified
- Certificate and inspection agreed before order
Oil, gas & process
Oil, gas and process projects require pipe, plate and corrosion-resistant grades to demanding standards. Zhongbo sources to the project specification with the mill certificate — and 3.2 or witnessed inspection where the contract requires it.
- Steel — pipe and plate to process standards
- Corrosion-resistant and specialty grades (incl. nickel, titanium) where specified
- 3.2 certificate or witnessed inspection where required

Standards & compliance
Supplied metal materials are sourced against the standard the buyer specifies — ASTM, EN, GB/T, JIS or a project specification — with the applicable grade, dimensions and origin confirmed per order. Zhongbo does not manufacture these materials; it sources them from identified mills and provides the mill documentation the project requires. An EN 10204 3.1 mill certificate is provided as standard; a 3.2 certificate or third-party / witnessed inspection is arranged where the project requires it.
Why metal materials buyers choose Zhongbo
Fabricators, EPC and project procurement teams and distributors source metal materials through Zhongbo because the supply chain and its documentation are handled to a single account. What sets the service apart:
- Mill identity, grade, dimensions and origin confirmed before order acceptance for every supplied item.
- One supply and documentation contact for steel, aluminium and copper across a project's forms and grades.
- Sourcing against the buyer's standard and approved-mill list where a project mandates one.
- EN 10204 3.1 mill certificate as standard; 3.2 or witnessed inspection where required.
- Clear manufacture-vs-supply account: Zhongbo represents itself as the supply contact, never as the mill.

Frequently Asked Questions
Does Zhongbo produce these metal materials?
No. Metal materials are an additional supply category, sourced from confirmed mills. Zhongbo confirms the mill, grade, dimensions and origin before order acceptance and provides the mill documentation you require, acting as the supply and documentation contact rather than the mill.
Which industries do you supply metal materials for?
Construction and infrastructure, power/energy and grid, manufacturing and fabrication, marine and shipbuilding, and oil, gas and process. The form and grade — steel, aluminium or copper in plate, bar, tube, strip or profile — is sourced to your application and standard.
Which certificate types can you provide?
An EN 10204 3.1 mill certificate is provided as standard; a 3.2 certificate or third-party / witnessed inspection is arranged where the project requires it. Confirm the certificate type in your RFQ so it is agreed before the order is placed.
Can you meet a specific standard or approved-mill list?
Yes. Send the standard and any approved-mill list the project mandates; the applicable grade, dimensions, origin and documentation are confirmed against your specification before the order is accepted.
How do I get a quote?
Use the Metal Materials RFQ Checklist to send the material form and grade, dimensions and tolerances, standard, quantity, certificate and destination port. The more precisely these are stated, the faster and firmer the quote.
