About Kbb International Co., Ltd. - Cupboards, Doors, Gates, Grills & Windows Supplier in China

Kbb International Co., Ltd. operates from China and currently lists twelve active products. The catalogue spans the categories Cupboards, Doors, Gates, Grills & Windows and Safety & Security Equipment, featuring turnstiles, revolving doors, sliding door operators and related hardware. Specific items include Slide Gate Turnstile, Wing Gate Turnstile, Three Arm Turnstile, Full Height Turnstile and Swing Gate Turnstile, as well as automatic door solutions such as 2 Wing Automatic Revolving Door (HS code 7308.90) and Automatic Revolving Door (HS code 8479.89). Materials range from aluminum alloy frames with tempered glass panels to steel housing with aluminum rails and plastic gear components. The product set also includes interior automatic doors (HS code 8302.41) and hermetic sliding doors (HS code 7308.30) built with galvanized steel, EPDM rubber seals and tempered safety glass of 10‑12 mm thickness.

The listed HS codes cluster in four tariff headings: 7308 for doors and windows of metal, 8302 for metal doors, 8479 for automatic machines and parts, and 7308.30 for safety glass assemblies. Each product description identifies the primary material - aluminum alloy, steel, tempered safety glass, or EPDM rubber - providing buyers with clear material composition. The catalogue does not disclose additional specifications such as load capacity or fire rating, which are typical technical parameters for this sector. The focus on both manual turnstiles and motor‑driven revolving or sliding doors reflects a breadth of access control and architectural hardware solutions. The absence of listed certifications suggests that buyers should verify compliance documents before purchase.

Product Range and Specialties of Kbb International Co., Ltd.

The product portfolio includes five types of turnstiles - Slide Gate, Wing Gate, Three Arm, Full Height and Swing Gate - commonly used in high‑traffic facilities for crowd control. In the door segment, the supplier offers 2 Wing Automatic Revolving Door, Automatic Revolving Door, All Glass Revolving Door, Automatic Sliding Door (Electronic Inductive Door), Hermetic Sliding Door, Sliding Door Operator and GI3000 Interior Automatic Door. Typical industry grades for these items involve aluminum alloy series 6000 (e.g., 6063‑T5) for frames, hot‑dip galvanized or stainless steel for structural members, and tempered safety glass meeting ISO 1288 with thicknesses of 10 - 12 mm. Turnstiles are frequently designed to comply with EN 15635 for durability and fire resistance, while automatic doors often meet EN 12453 for impact resistance and EN 16310 for fire protection. Buyers in this segment also look for CE marking, UL 294 for access control, and ISO 9001 quality management certification.

Standard specifications for motorized door systems include a torque rating of 5 - 15 Nm for sliding mechanisms, a control voltage of 24 V DC, and a sensor response time under 0.5 seconds. For revolving doors, the typical speed is 0.5 - 1 m/s with a minimum clearance of 900 mm. Glass panels are usually laminated or tempered to achieve a safety impact resistance of 150 kPa. These technical benchmarks help buyers compare the Kbb catalogue against global norms.

Trade and Export Information - Kbb International Co., Ltd.

China is a leading exporter of metal doors, revolving door systems and security turnstiles, supplying markets across Southeast Asia, the Middle East, Europe and North America. The HS‑code families represented - 7308, 8302 and 8479 - are subject to standard customs duties and often require importers to present CE or UL certificates, fire‑rating test reports and material safety data sheets. Buyers typically arrange shipments in 20‑ft or 40‑ft containers, with products packed on wooden pallets and protected by shrink‑wrap or corner bracing to prevent frame deformation.

Commonly requested certifications for these categories include CE marking for mechanical safety, ISO 9001 for quality management, and fire‑resistance certificates such as EN 16310 for doors. Inspection agencies like SGS or Bureau Veritas are frequently engaged to verify compliance before loading. Incoterms such as FOB Shanghai or CIF destination ports are standard practice for Chinese manufacturers. Seasonal demand spikes occur in the construction boom periods of Q2 - Q3, influencing lead times and container availability.

Sourcing from Kbb International Co., Ltd. - Buyer Guidance

When sourcing turnstiles or automatic doors from Kbb International, buyers should request detailed material data sheets specifying aluminum alloy series, steel coating grade and glass tempering standards. Test reports for load endurance (e.g., 500 kg for turnstile frames) and fire‑rating (30 min or 60 min) are typical documents that help verify suitability for public buildings.

Samples of the door frame or a small glass panel can be requested to assess finish quality and dimensional tolerances. Verify that the supplier can provide CE or UL certificates, ISO 9001 audit reports and, if required by the importing country, a Chinese export inspection certificate. Confirm minimum order quantities, which often start at one container load for motorized units, and clarify lead times that can range from 30 to 60 days depending on customization.
