AI-Powered supplier vetting

SummaryThe supplier is not identified as a professional technical supplier and does not provide 3D software design, ODM, or overseas agent services. It offers broad customization, including sample-, design-, full-, minor-, and flexible customization, and provides OEM services for well-known brands. Management certifications include ISO9001:2015, ISO45001:2018, and ISO14001. However, after-sales and quality-system weaknesses are indicated by the absence of written complaint-handling and corrective-action procedures, lack of raw-material traceability, and packing-staff-only finished-product checks. The supplier reports in-stock capability, lead times within 15 working days in both peak and off-season, and 11 years of export experience. Innovation evidence is limited: one R&D engineer, no new products in the past year, no ODM, and no SDK. Customer evidence includes an 80%–100% repeat-buyer preference, but no Fortune 500 cooperation.

Supplier typeThe supplier explicitly states that it is not a professional technical supplier and does not provide 3D software design services. It also does not offer ODM or SDK-supported R&D services, although it provides OEM services for well-known brands.

CertificationsThe supplier reports holding ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications. These stated certifications provide explicit evidence of certification coverage.

After-Sales capabilityNo written procedures or records exist for corrective and preventive actions or effective customer-complaint handling. Quality assurance is reported, but the absence of documented service processes is an explicit weakness.

R&D capabilityInnovation capability appears limited: the supplier had no new products in the past year, has one R&D engineer, does not offer ODM, and has no available SDK. These explicit data points indicate a deficiency in current product-development capability.

Customization capabilityThe supplier explicitly offers customization from samples, full customization, customization from designs, minor customization, and flexible customization. This is direct evidence of broad customization capability despite the absence of 3D software design services.

Client casesThe supplier provides OEM services for well-known brands and reports an 80%–100% repeat-buyer preference. However, it reports no cooperation with Fortune 500 companies, so the customer-case evidence is positive but limited in scope.

Product Q&A

Q:What is a U Head Jack Base, and what is its main function?

The U Head Jack Base, also called U-top screw jack, is a key adjustable fitting for scaffolding and formwork systems. It sleeves on top of scaffolding vertical poles, with a U-shaped fork to hold timber beams, steel joists or I-beams. It realizes flexible vertical height adjustment to level and support concrete formwork during construction. It matches ring-lock, cuplock and frame scaffolding systems widely.

Q:What other names does this product have?

It has multiple industry aliases: U jack, U-head screw jack, adjustable U top jack, formwork U jack, U fork jack, top U jack, JACK-BASE U head (the standard export name you use).

Q:What raw material is used for the U head jack?

The whole product is made of Q235 carbon structural steel, which has stable compression and bending resistance to meet construction load requirements.

Q:What surface anti-rust treatments are available? What's the difference?

Two mainstream galvanizing options: 1. Hot-dip galvanized: Thick zinc coating, excellent anti-corrosion, suitable for outdoor, coastal, humid construction sites; long service life. Higher cost. 2. Electro-galvanized (cold galvanized): Smooth bright surface, lower cost, fit for short-term indoor projects. We support customized painting finish as per client demands.

Q:Where can this U head jack be used?

Widely used in: - Civil residential & commercial building floor, beam, column formwork support; - Municipal projects: Bridges, viaducts, box girder formwork bracing; - Infrastructure: Subways, tunnels, underground pipe gallery support frames; - Temporary works: Stages, heavy-duty temporary working platforms.
