Frequently Asked Questions
What are the main differences between manual and electric compact shelving systems? How should you choose?
The manual dense rack relies on manual drive, with a simple structure and low cost, suitable for units with limited archives and budgets; The electric dense rack is driven by a motor and equipped with an intelligent control system. It can be electrically opened, stopped, and positioned, making it easy to operate and suitable for high-frequency use in large archives, libraries, and other places. When making a choice, it is necessary to consider the budget, warehouse area, frequency of use, and intelligent requirements comprehensively.
What are the ground requirements for installing the tracks of a compact shelving system?
The dense rack track requires high ground flatness, and it is usually recommended that the ground flatness error be within ± 3mm/㎡. Before installation, it is necessary to confirm that the ground has been hardened and reserve track slots or embedded steel plates. If the ground is uneven, it needs to be leveled first, otherwise it will affect the smooth operation and service life of the dense frame.
What is the typical thickness of the steel sheet used in steel file cabinets? How can you determine whether the quality is good or bad?
The standard thickness of steel sheet used for national standard steel file cabinets is typically 0.6–0.8 mm, while load‑bearing components such as shelves can reach 1.0–1.2 mm. To assess quality, you can consider the following aspects: ① Whether the steel sheet thickness meets the required standards (check the inspection report or measure it yourself); ② Whether the coated surface is uniform and smooth, with no sagging or dripping; ③ Whether the cabinet doors open smoothly and without noise; ④ Whether the welds are secure and free of burrs; ⑤ Whether the product has obtained national 3C certification and ISO quality system certification.
How much weight can a compact shelving unit hold? How many kilograms can each shelf accommodate?
The load capacity of each shelf in a standard compact shelving unit ranges from 80 to 120 kilograms, depending on the steel plate thickness, structural design, and layout of the shelf reinforcement ribs. All compact shelving units manufactured by our company undergo load testing; customers can choose reinforced shelves or denser support structures based on the weight of the items they plan to store.
How can steel cabinet products be protected from rust? What are the advantages of the spray coating process?
The company is equipped with a large, nine-station automatic painting line, with the following process sequence: degreasing → water rinsing → phosphating → water rinsing → drying → electrostatic powder coating → high‑temperature curing. Phosphating forms a dense phosphate film on the steel plate surface, enhancing its rust‑resistance; after epoxy polyester powder coating and high‑temperature curing, the coating exhibits strong adhesion, excellent corrosion resistance, and superior aging resistance, making it highly unlikely to rust even under normal operating conditions over many years.
Can compact shelving and bookshelves be custom‑made to special specifications? How long does the process take?
Yes, we can handle the production of office equipment with custom specifications, including non‑standard dimensions, special colors, and modifications such as increased height or depth. Our standard customization process is as follows: requirement consultation → drawing confirmation → sample production → mass production, with a typical lead time of 15–30 days, depending on the complexity of the project.
Does the product have any environmental certifications? Does the formaldehyde emission level meet the relevant standards?
The company has obtained ISO 14001 international environmental management system certification, and its steel products themselves are free from harmful substances such as formaldehyde. For products that include wooden components—such as wooden panel bookshelves—the wood panels used all comply with the national E1-level environmental standards, with formaldehyde emissions no more than 0.124 mg/m³; relevant test reports can be provided.
How long is the product warranty period? What is the after-sales service system like?
The company adheres to the principle of “comprehensive after-sales service.” The standard warranty period for our products is 1–3 years (subject to the terms stipulated in the contract), during which non‑human‑caused damage will be repaired or replaced free of charge. We provide after-sales support nationwide, responding promptly upon receipt of repair requests; for remote areas, we can offer telephone guidance or coordinate with local service providers to handle issues.
What could be the reasons if a compact shelving system runs unevenly or makes unusual noises?
Possible causes include: ① Foreign objects in the track or track deformation; ② Bearing oil deficiency or wear; ③ Loose or worn sprockets and chains; ④ Ground settlement causing the frame to tilt. It is recommended to regularly clean the track and lubricate it with oil, and to inspect the transmission components every six months. If the problem persists, you can contact after-sales service for on-site maintenance.
After purchasing the compact shelving unit, does the manufacturer handle the installation? How long does the installation take?
The company offers free on-site installation services, with a professional installation team carrying out work according to the blueprints. The installation duration depends on the batch size; for projects involving fewer than 1,000 units, the typical installation time is 3–7 days. After installation is complete, a commissioning and trial run will be conducted to ensure the product operates normally, and basic user training will be provided to operating personnel.
