FAQ

Q: What are the primary services and business scope of GennHann Stainless Steel?

A: Founded in 1980 with over 40 years of industry experience, GennHann is a specialized precise cutting center. Our core expertise lies in precision slitting, shearing, and polishing (sandblasting) technologies. We are an ISO-certified company and a designated material supplier for TOYOTA. We supply 200, 300, and 400 series stainless steel coils, sheets, strips, and pre-painted (coating) coils. We provide customized precision cutting for high-end industries, including semiconductors, chemical engineering, food processing, and automotive components.

Q: What surface finishes can GennHann Stainless Steel provide, and is protective film available?

A:

We offer a full range of surface solutions from industrial foundations to aesthetic architectural finishes. To protect materials during processing and installation, we provide single or double-sided filming services (e.g., Blue Film, Black & White Film, and Laser Film) to ensure zero scratches.

Surface FinishProcess & CharacteristicsCommon Applications
NO.1Hot-rolled, heat-treated, and pickled. Heat & corrosion resistant.Industrial tanks, chemical devices.

BA (Bright)Bright annealed. Highly reflective with a mirror-like luster.Home appliances, decorative materials, mirrors.
NO.3 Polished with 100-120 grit. Features short, coarse grains.Architectural decor, electrical products.
NO.4 Polished with 150-180 grit. Finer grains than NO.3.Kitchen & food equipment, building renovation.
HL (Hairline)Continuous linear grains. Elegant texture, hides scratches well.Elevators, escalators, storefronts, facades.
SB (Scotch Brite)Polished with 150-180 grit non-woven belts. Soft texture.High-end appliances, precision panels.

Q: What are the customized size ranges (thickness, width, length, and tolerances) that GennHann Stainless Steel can supply?

A: “Customization” is GennHann’s core orientation. We provide precise thickness, width, and length based on your technical drawings to optimize material utilization and reduce your production costs. While standard sizes offer shorter lead times, special specifications can be arranged through our professional slitting and shearing lines.

Q: Which international standards do GennHann's Stainless Steel products comply with?

A: Our products comply with major global standards, including ASTM, JIS, and EN. For example, Grade 304 corresponds to ASTM A240 304, JIS SUS304, or EN 1.4301. We assist clients in cross-referencing different international standards to ensure total compliance with project specifications.

Q: How does the Quality Control (QC) process work at GennHann Stainless Steel?

A: Before shipment, GennHann executes a rigorous QC procedure: verifying Heat Numbers against MTCs, measuring dimensional tolerances, and inspecting surfaces for scratches or contamination. For value-added services like slitting, shearing, or polishing, every step is recorded in our process inspections to maintain premium quality.

Q: What testing and certification documents can GennHann Stainless Steel provide?

A: We provide Mill Test Certificates (MTC) in EN 10204 3.1 format, which include Heat/Lot numbers, chemical composition, and actual mechanical property test results to ensure full traceability. For critical applications, GennHann can also coordinate with third-party inspection agencies for additional testing.

Q: What is the typical Minimum Order Quantity (MOQ) and lead time at GennHann Stainless Steel ?

  • A:
    MOQ: Varies by product type, grade, and specification. Standard grades and regular sizes allow for smaller order quantities, while customized processing offers flexible solutions based on project scale.
  • Lead Time: Stock materials for basic cutting offer the fastest delivery. Special processing or mill production requires a longer duration. GennHann provides estimated lead times based on your destination and technical requirements.

Q: Why is there a large price gap between suppliers, and what is the advantage of choosing GennHann Stainless Steel?

A:Price differences typically stem from material grade purity, thickness tolerance precision, surface quality, and after-sales risk management. GennHann Stainless Steel encourages clients to compare standards and reliability side-by-side. Choosing GennHann avoids risks such as “under-gauge” thickness or inferior surfaces, ensuring you receive the best overall value and project security.
