Plain answers about the material, the company, and what a form submission does and does not mean.
Cement, cementitious materials, and bulk industrial commodities. Raw granulated blast furnace slag is one cementitious material in that scope. Each shipment is quoted against the buyer’s specification. This site does not publish prices.
No. GBFS is the unground, sand-like granule from water-quenched blast-furnace slag. GGBFS is that material after drying and fine grinding. When the requirement is GBFS, we source the raw granule, not ground slag cement.
ASTM C989/C989M covers slag cement, the finely ground product, for use in concrete and mortars, including grades 80, 100, and 120. It does not automatically certify raw GBFS. GulfGran does not claim ASTM certification.
No. We do not manufacture cement or steel, and we do not operate blast furnaces, grinding plants, vessels, or port terminals. We source material and coordinate supply with the parties who do that work.
Houston, Texas, USA. A street address and phone number are published only when the company provides them. Use the inquiry form to reach the commercial team.
Qualified buyers of cement, cementitious materials, and bulk industrial commodities. For raw GBFS, that includes processors who can receive and grind the granule. The site describes markets. It does not publish a customer list or imply a contract.
We can coordinate a representative sample and the documents a buyer requests, subject to the producer’s availability and the buyer’s protocol. Technical approval belongs to the buyer.
Depending on the shipment: a supplier certificate of analysis, an SDS when the producer issues one, origin and weight papers, and an independent laboratory report when one has been commissioned. We pass documents through. We are not an accredited laboratory.
No. Price depends on specification, origin, quantity, Incoterms, and timing. Use the quote request. A page on this site is not an offer.
Yes. Use the contact form and select supplier inquiry. Include the material, the origin region, and the documents you can provide. Those introductions are reviewed privately and are not published as supply.
The basis is agreed per transaction. The quote form asks for a preference, including FOB, CFR, CIF, DAP, or another basis. Nothing is fixed until a contract says so.
No. We source cement, cementitious materials — including raw GBFS — and other bulk industrial commodities. A published note exists for raw GBFS. Other materials are quoted against the specification you send, not from a standing catalog.
