Silent Casters Moving File Cabinets Shelf System for Office Document Organization

1. Ultra-Quiet Mobile Performance: Equipped with 4 high-density polyurethane silent casters (2 with brake function), the noise during movement is ≤ 35dB (equivalent to the volume of a whisper), avoiding disturbing colleagues in quiet office environments; the casters have a load-bearing capacity of 50kg each, ensuring stable movement even when the cabinet is fully loaded.

2. Efficient Document Classification: Designed with 3-4 layers of adjustable shelves (height adjustable in 50mm increments) and 1-2 lockable drawers; shelves are suitable for storing large-volume documents (e.g., A3 folders, bound reports), while drawers are used for small items (e.g., stationery, confidential files), realizing "classified storage + quick access".

3. Sturdy & Durable Structure: Made of 0.8-1.0mm thick cold-rolled steel (Q195), the cabinet body has a maximum load-bearing capacity of 150kg; the surface is smooth and not easy to scratch, and can resist daily collision and wear, with a service life of 8-10 years.

4. Space-Saving Design: The overall size is 800×450×1200mm (length×depth×height), which can be placed against the wall or in the corner of the office; the compact structure does not occupy extra space, and multiple cabinets can be stacked or arranged in a row according to needs.

5. Humanized Details: The shelf edge is designed with a 20mm high anti-slip baffle to prevent documents from falling during movement; the cabinet handle adopts an ergonomic arc design, which is comfortable to hold and easy to push and pull; the lockable function of the drawer ensures the safety of confidential documents.

1. Steel Material Cutting: Select high-quality Q195 cold-rolled steel coils, and use a CNC shearing machine to cut them into standard plates (accuracy error ≤ 0.3mm) according to the design size, ensuring the consistency of each component.

2. Sheet Metal Forming: Use a 600-ton hydraulic press to punch and bend the steel plates into cabinet bodies, shelves, and drawers; the bending angle error is ≤ 1°, and the edges are treated with deburring to avoid sharp burrs scratching hands.

3. Surface Treatment: Conduct 3-stage pretreatment (degreasing → derusting → phosphating) to remove oil and rust on the steel surface; then apply electrostatic powder coating (epoxy resin material) and bake at 180-200℃ for 25 minutes, forming a uniform and smooth coating (thickness ≥ 60μm) with strong adhesion and corrosion resistance (salt spray test ≥ 200 hours).

4. Caster & Component Assembly: Assemble the polyurethane silent casters to the bottom of the cabinet body (adopting rivet fixing, pull-out force ≥ 300N); install adjustable shelf brackets, lockable drawer slides, and handles; each component is tested for tightness to ensure no looseness.

5. Finished Product Inspection: Test the caster movement (1000 times of back-and-forth movement without abnormal noise or damage), shelf load-bearing (1.2 times the rated load for 24 hours without deformation), and drawer lock function (100 times of opening and closing without failure) to ensure qualified products.

1. Corporate Administrative Departments: Used to store administrative documents (e.g., employee contracts, financial reports, meeting minutes); the silent casters allow the cabinet to be moved to the desk side for document retrieval, improving work efficiency.

2. Small & Medium-Sized Offices: Suitable for small office spaces (e.g., 10-20㎡); the compact design saves space, and the multi-layer shelves can meet the storage needs of multiple employees’ documents, avoiding messy document stacking.

3. Collaborative Workspaces/Co-working Spaces: In shared office environments, the mobile cabinet can be moved between different workstations according to team needs; the lockable drawer ensures the privacy of each team’s documents.

4. Educational Institutions (Schools/Training Centers): Used in teacher offices to store teaching plans, student homework, and examination papers; the anti-slip baffle and silent casters are suitable for the quiet and busy office environment of schools.

5. Medical Institutions (Clinics/Small Hospitals): For storing non-confidential medical documents (e.g., patient visit records, medical supplies lists); the corrosion-resistant coating is easy to clean and can resist the impact of daily disinfection.

1. Professional Office Storage Design: We have 10+ years of experience in office furniture design, and our team will optimize the cabinet size, shelf height, and caster configuration according to the characteristics of office document storage (e.g., the height of the shelf is adjusted to the height of the A4 folder), ensuring that the product is more in line with office usage habits.

2. Strict Quality Control: From raw material procurement (each batch of steel has a quality inspection report) to finished product delivery (100% full inspection), we comply with ISO 9001 quality management system and GB/T 3325-2017 "Office Furniture - Steel Furniture" standard, and each product has a unique quality traceability code.

3. Customization Service: We support personalized customization, such as adjusting the number of shelves (3-5 layers), changing the cabinet color (white, gray, black, etc.), and adding logo printing; the minimum order quantity for customization is 10 pieces, which can meet the personalized needs of enterprises of different sizes.

4. Cost-Effective & Fast Delivery: As a direct manufacturer, we eliminate the middleman markup, and the product price is 15%-20% lower than that of distributors; we have a stock of 5,000+ units, and the delivery time for standard products is 3-5 working days; for customized products, the delivery time is controlled within 10-15 working days.
