About Dalian Oak International Co,.Ltd. - Agriculture Supplier in China

China hosts six active product listings from Dalian Oak International Co,.Ltd., all classified under refractory materials used in high‑temperature industrial processes. The catalogue includes Magnesia Alumina Zirconia bricks, Magnesia‑Alumina Spinel brick (HLMLJ), High Pure Magnesia, Fused‑Rebonded Magnesia‑Chrome Bricks, Direct‑Bonded Magnesia‑Chrome Bricks and Magnesia‑Calcium Bricks, each described by its material composition rather than a brand name or certification claim.

These products fall within the broader refractory brick segment, which is typically governed by standards such as ASTM C617 for magnesia bricks and EN 1561 for high‑temperature refractory products. Buyers encountering these items should expect specifications that detail chemical purity (e.g., magnesia content ≥ 95 %), density, compressive strength and dimensional tolerances, all of which are standard parameters in the industry.

Product Range and Specialties of Dalian Oak International Co,.Ltd.

The supplier’s six entries cover a spectrum of magnesia‑based refractory bricks, ranging from alumina‑zirconia mixes to chrome‑bonded variants. In the global refractory market, magnesia bricks are graded by purity (often expressed as 95 % MgO or higher) and by the presence of additives such as alumina, spinel or calcium that modify thermal shock resistance and corrosion resistance. Typical dimensions include standard sizes of 1 m × 0.5 m × 0.1 m, and bulk shipments are measured in tonnes per container, with 20‑ft containers holding roughly 12‑14 tonnes of brick depending on packaging.

Industry practice also distinguishes between fused‑rebonded and direct‑bonded production methods; fused‑rebonded bricks generally exhibit higher compressive strength (up to 150 MPa) and lower porosity, while direct‑bonded bricks are valued for rapid production cycles. Buyers often request material data sheets that list the exact MgO, Al₂O₃, Cr₂O₃ and CaO percentages, as well as test results for refractoriness under load (RUL) and thermal conductivity.

Trade and Export Information - Dalian Oak International Co,.Ltd.

China is a major exporter of refractory bricks, supplying steel mills, cement plants and glass manufacturers across Asia, the Middle East and Eastern Europe. The HS chapter 68 (specifically heading 6810) captures most magnesia‑based refractory products, and customs authorities in importing countries frequently require conformity to ASTM or ISO test reports and, where applicable, compliance with local environmental regulations such as the EU REACH framework.

Typical export logistics involve loading bricks on pallets or bulk bags, secured in shipping containers with moisture‑proof liners to prevent degradation. Common Incoterms are FOB Dalian Port or CIF destination ports, with buyers arranging for pre‑shipment inspection by agencies like SGS or Intertek to verify chemical composition and mechanical properties before cargo release.

Sourcing from Dalian Oak International Co,.Ltd. - Buyer Guidance

When sourcing from Dalian Oak International Co,.Ltd., buyers should request a recent chemical analysis certificate and a compressive strength test report for each brick type. Verification of the manufacturing process - whether fused‑rebonded or direct‑bonded - helps assess suitability for specific furnace conditions, and a sample of the finished brick can be used for on‑site trial fits before a full order is placed.

It is advisable to confirm the supplier’s ability to provide ISO 9001 or equivalent quality‑management documentation, even though such certification is not listed in the supplied facts. Buyers should also clarify the packaging format (e.g., wooden crates versus bulk bags), the maximum container load, and the anticipated lead time, which for refractory bricks from China typically ranges from 30 to 45 days after order confirmation.

What types of refractory bricks does Dalian Oak International Co,.Ltd. offer?

The catalogue lists six magnesia‑based bricks: Magnesia Alumina Zirconia bricks, Magnesia‑Alumina Spinel brick (HLMLJ), High Pure Magnesia, Fused‑Rebonded Magnesia‑Chrome bricks, Direct‑Bonded Magnesia‑Chrome bricks and Magnesia‑Calcium bricks.

Are technical specifications available for each brick type?

Buyers can request material data sheets that detail MgO, Al₂O₃, Cr₂O₃ and CaO percentages, as well as compressive strength, density and thermal shock resistance values.

Which certifications should a buyer ask for?

Typical requirements include ISO 9001 quality‑management certification, ASTM test reports (e.g., C617) and, where applicable, compliance statements for REACH or other regional environmental standards.

What is the usual minimum order quantity (MOQ) for these bricks?

Refractory bricks are commonly sold in container loads; an MOQ of one 20‑ft container (approximately 12‑14 tonnes) is standard, though smaller bulk‑bag shipments may be negotiated.

What is the typical lead time from order to shipment?

Lead times from Chinese refractory manufacturers normally range from 30 to 45 days, dependent on production scheduling and required pre‑shipment inspections.

How are the bricks packaged for export?

Standard packaging uses wooden crates or moisture‑proof bulk bags, stacked on pallets to maximize container space while protecting against breakage and moisture ingress.

Which Incoterms are commonly used for shipments?

FOB from Dalian Port and CIF to the buyer’s destination port are the most frequently applied terms for these products.

Which markets commonly import magnesia‑based refractory bricks?

Key importers include steel producers in South‑East Asia, cement factories in the Middle East and glass manufacturers in Eastern Europe, all of which require high‑purity magnesia bricks for furnace linings.
