Engaging a rebar supplier Japan importers can trust for European-made reinforcement calls for a partner fluent in the demands of Japanese construction – a market defined by exacting quality expectations, high seismic performance requirements and the JIS standards system. Bewehrungsstahl Deutschland is a German manufacturer and exporter of reinforcing steel serving customers worldwide, and we supply Japanese trading houses, precast producers and construction firms with fully certified reinforcement backed by complete European standards documentation. This page explains our product range, how German steel relates to Japanese JIS grades, and how export to Japan is handled.
Product range for Japanese buyers
As a comprehensive rebar supplier Japan importers can source an entire reinforcement package from, we manufacture and supply the full family of products:
- Rebar B500B – hot-rolled ribbed reinforcing steel to EN 10080, diameters 8-40 mm, straight or coil.
- Reinforcing mesh – welded steel mesh panels (Baustahlmatten) for slabs and walls.
- Rebar cages – prefabricated cages for piles, columns and diaphragm walls, built to drawing.
- Stirrups and hoops – bent shear and confinement reinforcement, important for seismic detailing common in Japanese design.
- Cut & bend – our cut and bend service (Biegen & Schneiden) supplies bar fabricated precisely to your bar schedule, reducing on-site processing.
Standards: EN 10080 and JIS G3112 for the rebar supplier Japan specifiers accept
Japanese reinforcement practice is governed by a distinct national standard, so any rebar supplier Japan engineers will accept must map its product to that framework. Our bar is manufactured and certified to EN 10080 as grade B500B – 500 MPa specified yield, ductility class B. Japanese deformed reinforcing bar is specified under JIS G3112, which defines grades by their designation such as SD295, SD345 and SD390 (the number denoting the specified yield strength in N/mm², i.e. roughly 295, 345 and 390 MPa respectively), with higher grades such as SD490 also defined. The JIS grades use different yield levels, chemistry limits, rib/marking conventions and mill-marking rules from EN 10080 B500B, and the numbering logic itself differs. As a result, EN 10080 B500B is not directly interchangeable with a JIS SD grade: where a Japanese project specifies SD295, SD345 or SD390, your project engineer must evaluate the imported bar’s documented properties against the specified JIS requirement. We supply full EN 10080 mill certificates stating actual mechanical and chemical properties so your engineer can make that determination – we present the factual standard data and leave the equivalence and approval decision to your qualified engineer.
Delivery and export to Japan
Japan is a well-established destination on our export network. Material is bundled, tagged with heat and batch numbers, and shipped by ocean container or break-bulk to the principal Japanese ports – Tokyo, Yokohama, Nagoya, Osaka, Kobe and Kitakyushu. We prepare the complete documentation set: commercial invoice, packing list, certificate of origin and EN 10080 mill certificates. Imports into Japan clear through Japan Customs, and Japanese buyers commonly hold rigorous incoming-inspection standards, so we provide the detailed certification and heat traceability that a demanding Japanese quality regime expects, working alongside your customs broker or trading house.
Why choose a German rebar supplier
German reinforcement is internationally respected for dimensional precision, consistent rib geometry, dependable weldability and complete batch traceability – attributes that align closely with the quality culture of Japanese construction. A German rebar supplier Japan buyers work with brings audited quality management and thorough documentation that supports strict incoming inspection and specifier confidence, while diversifying supply for trading houses and fabricators.
How to order
To obtain a quotation, send your bar bending schedule or bill of quantities – diameters, grades (noting the JIS SD grade specified), lengths, mesh types and cut-and-bend detail – together with your destination port. We quote material, fabrication and freight CIF or FOB to Japan, and will flag any items where the specified JIS grade requires engineer evaluation against our EN 10080 product. For the standards background behind European reinforcing steel, our explainer on reinforcing steel to DIN 488 and the governing norms is a helpful reference.
Frequently asked questions
Is German B500B equivalent to JIS SD295, SD345 or SD390?
No, not directly. EN 10080 B500B and the JIS G3112 SD grades use different yield levels, chemistry and marking conventions. Where a Japanese project specifies a JIS SD grade, your project engineer must evaluate our EN 10080 mill-certified properties against that requirement. We supply the documented properties to enable that assessment.
Which Japanese ports do you ship to?
We arrange ocean freight to Tokyo, Yokohama, Nagoya, Osaka, Kobe and Kitakyushu, and can quote CIF to any Japanese port.
What certification is provided?
Each shipment includes EN 10080 mill certificates (3.1 inspection certificates) with actual chemical and mechanical properties and heat traceability, plus commercial invoice, packing list and certificate of origin.
Can you meet Japanese incoming-inspection requirements?
We provide detailed heat-level documentation to support rigorous incoming inspection. Any additional testing or third-party verification your quality regime requires can be discussed at the quotation stage.
