If you are looking for a reliable carbon steel manufacturer, the short answer is this: choose a partner that combines in-house production lines, ready stock, international standards and documented quality control. Shandong Ruixiang Steel Group Co., Ltd. is a steel manufacturer in China with more than 20 years in the steel industry, more than 10 production lines and an ISO 9001-certified quality system. We supply carbon steel plate, coil, pipe and structural sections to buyers in domestic and overseas markets, and we support each order with cutting, processing, testing and export packaging.
This guide explains what we make, how we control quality, how fast we can deliver, and what current market conditions mean for your next carbon steel purchase.
Who We Are: A Carbon Steel Manufacturer Based in Shandong
Ruixiang Steel Group is a comprehensive steel enterprise that integrates production, sales, processing, cutting and transportation. Our mill represents a total investment of 1,020 million yuan and employs more than 500 people, with technical personnel making up over 40% of the workforce. That ratio matters to buyers: technical staff are the people who check chemistry, verify dimensions and solve problems before goods leave the factory.
According to our company records, the group’s production sales exceeded 10 million tons in 2020. We keep more than 10,000 tons of pipes, plates, bars and profiles in stock throughout the year, which gives us stable supply capacity even when market demand shifts quickly.
We also work with leading Chinese mills listed as our partners, including Shan Steel, Shougang Group, Rizhao Steel, Ansteel, Laigang Group and Baowu Steel. This network helps us source specific grades and sizes when a project needs more than our own lines produce, so buyers can consolidate several items with one carbon steel supplier.
Our business philosophy is simple: “customer first, quality first.” It guides how we quote, produce and follow up on every order.
Carbon Steel Products We Manufacture and Supply
Our carbon steel products cover the main categories used in construction, energy, manufacturing and infrastructure. Each category below links to a dedicated product page with full specifications.
Carbon Steel Plate and Coil
Our carbon steel sheet and coil range is produced on more than 10 lines for carbon, wear-resistant and weather-resistant steel plate, with a daily output of thousands of tons. Common stock grades include ASTM A36, A283, SS400, S235, S355, Q235 and Q345.
Beyond standard structural plate, we supply low-alloy plate (such as A572 Gr.50 and S355 series), shipbuilding plate (grades A, B, D, E, AH32/36 and higher-strength classes), bridge plate, pressure vessel plate and high-rise building plate.
Carbon Steel Pipe
As a carbon steel exporter, pipe is one of our most requested product lines. Our carbon steel pipe range includes:
- Seamless steel pipe, including precision seamless pipe, large-diameter seamless pipe and A106 Gr.C pipe for high-temperature service in plants and refineries
- ERW steel pipe, including A53 ERW carbon steel pipe
- LSAW (DSAW) pipe for straight-seam large-diameter applications
- SSAW spiral pipe, outer diameter 219–3,620 mm, wall thickness 5–25.4 mm, length 3–12 m
- Square and rectangular tube to ASTM A500 Grade B, ASTM A513 and ASTM A36
- Galvanized steel pipe, both hot-dip and cold-galvanized
We also supply oil country tubular goods, including casing and tubing, couplings, drill pipe and pup joints.
Structural Steel Sections
Our structural steel range includes H beams for buildings, bridges and skids; C channels for general fabrication; steel angles; and steel sheet piles that interlock to form continuous retaining or water-retaining walls. Galvanized coil, color-coated coil and roofing sheet complete the range for construction buyers.
Quality Control You Can Verify
For overseas buyers, quality assurance is often the deciding factor when choosing a carbon steel manufacturer. Our system is designed to give you evidence, not promises.
Certified Management Systems
Our quality assurance system is certified to ISO 9001. An independent quality assurance department oversees every working procedure, so that manufacturing follows international technical delivery conditions such as ASTM/ASME, EN and API, as well as the customer’s own specification. We are also certified to OHSAS 18001 for occupational health and safety. Our plate products are approved annually by ISO 9001, CE and SGS. Our service page also lists third-party approvals from classification and inspection bodies, together with customer approvals from energy-sector clients.
In-House Destructive and Non-Destructive Testing
Our own laboratory performs a wide range of tests before shipment:
Every steel pipe is marked with the manufacturer name, product standard, material grade, heat number, pipe number, wall thickness, actual length and outer diameter. That traceability allows you to match each piece back to its mill test certificate.
Processing Services That Reduce Your Downstream Costs
Many buyers lose time and money by sending raw material to a third-party fabricator. As an integrated carbon steel supplier, we can deliver material closer to its final form. Our processing services include:
- Plate cutting: waterjet, laser, plasma arc, disc shear, sawing, step punching and grinding-wheel cutting, chosen to suit thickness and tolerance
- Tube cutting: cold sawing, band sawing and lathe cutting, selected according to production rate and required end condition
- Bending: compression, ram, roll and rotary draw bending, including pipe bends made to your drawings, sketches or samples
- Piping spool fabrication: prefabricated carbon steel and stainless steel spools (seamless or welded) built to your drawings, which helps reduce field installation costs
- Marking and painting: surface preparation, primer and coating according to project requirements
- Deep processing: heat treatment, chrome plating, copper plating and nickel plating
We can also print your logo on products and support OEM/ODM requirements.
Delivery Times, Export Packaging and Global Reach
Lead time is often more important than a small price difference. For common sizes, we can ship from stock in about 6 days. For special sizes that require new production, delivery is typically 35–45 days. Because we maintain large year-round inventory, we can respond quickly to urgent project orders and replenishment needs.
Every shipment uses standard export packaging. For pipe, tubes in one bundle share the same batch number, steel grade and specification, and long tubes (6 m or more) are secured with at least eight strapping bands. This reduces movement and bending damage during sea transport and handling.
Our quality management procedures have helped us serve customers in more than 100 countries. Our main plate customers are concentrated in South Asia and Europe, and our published shipment records include carbon steel coil exported to Turkey and stainless steel products shipped to the UAE, Brazil, Ecuador and Iran. You can review these projects on our showcase page.
How to Choose the Right Carbon Steel Manufacturer
Use this checklist when you compare suppliers:
- Production capability: Does the supplier run its own lines, or does it only trade? Ask for line count and output.
- Standards coverage: Can it produce to ASTM, EN, JIS and GB grades, and to your project specification?
- Testing evidence: Will it provide mill test certificates and accept third-party inspection?
- Stock and lead time: Is there ready inventory for common sizes, and what is the realistic lead time for new production?
- Processing: Can it cut, bend or fabricate to reduce your downstream work?
- Export experience: Does it understand export packaging, documentation and market-specific rules?
- After-sales support: Is there a clear process for handling claims after delivery?
Ruixiang Steel Group is built to answer “yes” on each of these points. If you are still comparing options, send us the same inquiry you send to other suppliers. A side-by-side comparison of specifications, test documents and lead times is the fastest way to judge value.
