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 an Adjustable Jack Base?

Adjustable Jack Base, also known as scaffolding base jack or leveling screw base, is a critical bottom fitting for all scaffolding systems. It is fitted under scaffolding vertical standards to level uneven ground, evenly disperse construction loads to the ground, and adjust the overall horizontal height of the scaffolding frame. It is always used together with U-head top jacks to form a full adjustable formwork support system.

Q:What raw material do you use for jack bases?

The entire jack base is made of Q235 carbon structural steel. This material delivers stable compression and bending resistance to meet heavy load requirements of building and bridge construction.

Q:Should I choose a solid screw rod or hollow screw rod?

The choice depends on your project load: - Solid screw rod: Higher compressive strength, for heavy-duty projects such as high-rise buildings, large-span bridges and viaducts; heavier weight and higher price. - Hollow screw rod: Lightweight and cost-saving, suitable for ordinary residential construction with medium bearing loads.

Q:Which scaffolding types match your adjustable jack base?

It fits all standard 48mm outer diameter vertical tubes, including ring-lock/disk lock scaffolding, cuplock scaffolding, frame scaffolding and kwikstage scaffolding.

Q:Where can adjustable jack bases be applied?

Widely used across multiple construction sectors: - Civil & commercial buildings: Floor, beam and column formwork scaffolding foundation support - Municipal & bridge engineering: Viaduct, box girder and bridge deck formwork leveling - Infrastructure: Subways, tunnels and underground pipe gallery temporary frames - Temporary works: Event stages, heavy-duty working platforms and exhibition support frames
