About Reven Industries - Fastener and Steel Component Supplier in India

India, with an active catalogue of nine fastener and steel component items, supplies a range of products that fall under the categories Bolts, Flanges, Steel Rods, Nuts, Clamps, Washers and Scaffolding. The catalogue lists Threaded Rods (HS code 7318.15) made from carbon steel grade 4.8/8.8, Hex Bolts (HS code 7318.15) of carbon steel grades 4.6‑8.8, Hex Nuts, Clamps (HS code 7307.99) fabricated from pre‑galvanized or electro‑plated carbon steel, Flat Washers and Spring Washers, U‑Bolts (HS code 7318.16) of carbon steel grades 4.6‑8.8, Scaffolding components, Flanges (HS code 7307.91) in carbon steel ASTM A105 or ASTM A350 LF2 as well as stainless steel 304/316, and Forging Parts (HS code 7307.19) of carbon or alloy steel with zinc plating.

The HS‑code families 7318 cover threaded fasteners such as rods, bolts and U‑bolts, while 7307 includes a broader set of forged steel items like clamps, washers, flanges and forged parts. All items are described by material grade and finish, indicating suitability for load‑bearing or corrosion‑resistant applications. The product list does not include explicit certifications, so buyers should verify compliance with relevant standards during procurement.

Product Range and Specialties of Reven Industries

Reven Industries’ catalogue includes threaded rods, hex bolts, hex nuts, clamps, washers, U‑bolts, scaffolding components, flanges and forged parts. In the fastener market, threaded rods and hex bolts are typically supplied to ISO 898‑1 grade 4.6, 5.6, 8.8 and 10.9, with dimensions ranging from M6 to M36 and lengths up to 3000 mm. Hex nuts follow the same grade system and are often measured by thread pitch and thickness according to DIN 934 or ISO 4032. Clamps and U‑bolts made from pre‑galvanized carbon steel usually meet ASTM A193 or EN 10253 specifications, with corrosion‑resistant coatings measured by zinc coating weight (g/m²). Flanges listed under HS 7307.91 are commonly produced to ASTM A105 (cast iron) or ASTM A350 LF2 (low‑temperature carbon steel) standards, with pressure classes such as PN10‑PN160 for pipe connections. Stainless steel 304/316 flanges follow ASTM A182 and are selected for higher corrosion resistance. Forged parts with zinc plating are often supplied to EN 10241 or ISO 683‑2 for alloy steel, with plating thickness verified by ASTM B633. Scaffolding components are typically hot‑rolled steel sections conforming to EN 1004 or IS 4675 standards for load‑bearing capacity.

Trade and Export Information - Reven Industries

India is a leading exporter of fasteners and forged steel components, shipping mainly to the Middle East, Africa, Southeast Asia and European markets. The HS‑code 7318 family is routinely inspected under customs regimes that require mill test certificates and, where applicable, compliance with ISO 9001 quality management systems. HS‑code 7307 items are often subject to anti‑dumping investigations and may require additional documentation such as a Certificate of Origin and a compliance statement for EN or ASTM standards. Buyers typically receive products packed in wooden crates on Euro pallets, with 20‑ft containers holding up to 25 tons of bolts or 30 tons of flanges, depending on packaging density. Common Incoterms for Indian fastener exporters are FOB Mumbai or CIF destination, with freight forwarders handling bulk steel cargo under standard marine insurance.

Sourcing from Reven Industries - Buyer Guidance

When sourcing from Reven Industries, buyers should request mill test reports that confirm chemical composition, tensile strength and hardness for each grade listed. For stainless steel flanges, a 3‑point bend test report and a surface finish inspection (roughness Ra) are customary. Verify that the supplier can provide material certifications such as ISO 9001 or equivalent, and confirm the coating weight for galvanized clamps and U‑bolts. Samples of representative sizes are advisable before finalising a bulk order, especially for critical load‑bearing applications. Clarify packaging details - typically bundles of 100 pieces for bolts, wrapped in anti‑rust film and palletised - and confirm the minimum order quantity and expected lead time, which for Indian fastener manufacturers often ranges from 4 to 8 weeks after order confirmation.

What fastener grades does Reven Industries offer for threaded rods and hex bolts?

The catalogue lists carbon steel grades 4.8/8.8 for threaded rods and grades 4.6 to 8.8 for hex bolts, which correspond to ISO 898‑1 strength classes commonly used in structural and mechanical applications.

Are mill test certificates available for the flanges?

Flanges are supplied in carbon steel ASTM A105, ASTM A350 LF2 and stainless 304/316; buyers should request mill test certificates that detail chemical composition, tensile strength and impact test results in line with ASTM A105/A350 or ASTM A182 requirements.

What coating standards apply to the clamps and U‑bolts?

Clamps are offered in pre‑galvanized or electro‑plated steel, while U‑bolts use carbon steel with zinc plating; typical industry practice is to verify coating weight according to ASTM B633 or EN 1460 specifications.

Which HS codes cover the products in the catalogue?

Threaded rods, hex bolts and U‑bolts fall under HS 7318 (with sub‑headings 7318.15 for rods and bolts, 7318.16 for U‑bolts). Clamps, flanges, washers and forged parts are classified under HS 7307 (7307.99 for clamps, 7307.91 for flanges, 7307.19 for forged parts).

What are the typical packaging and container loads for the bolts?

Bolts are usually packed in bundles of 100 pieces, wrapped in anti‑rust film, placed on Euro pallets and loaded into a 20‑ft container at approximately 25 tons, or a 40‑ft container at about 45 tons, depending on size range.

Which certifications should a buyer request before purchasing?

Buyers should request ISO 9001 quality management certification, mill test reports for each grade, and, where applicable, compliance certificates for ASTM or EN standards relevant to the specific product type.

What is the typical lead time for an order of flanges and welded forged parts?

Lead times for flanges and forged parts from Indian manufacturers generally range from four to eight weeks after order confirmation, depending on the required dimensions, material grade and any special surface treatment.
