Metal Folding Drying Rack is a foldable drying equipment made of high-strength metal materials (such as carbon steel, stainless steel or aluminum alloy), which realizes efficient use of space through retractable brackets and folding structures. Its design takes into account both load-bearing capacity and portability, and is suitable for home, industrial and commercial scenarios, especially for places with limited space or temporary drying.

Technical process

1. Material and process

Frame material: Q235 carbon steel (surface spray treatment) or 304 stainless steel, corrosion resistance increased by 50%, service life up to more than 8 years.

Connection process: The welding points are pickled and phosphated, with a load-bearing capacity of 50kg/layer (industry average 30kg), and the bracket uses 1.2mm thick metal pipes, which increases stability by 40%.

Folding structure: It adopts a hinged folding design, with an unfolded size of 180cm (length) × 60cm (width) × 170cm (height). The thickness after folding is only 8cm, saving 85% of space.

2. Core parameters

Load-bearing capacity: single-layer maximum load-bearing 15kg, total load-bearing 60kg (4-layer structure).

Layer height adjustment: The adjustable range of each layer is 25-40cm, suitable for clothes or materials of different sizes.

Mobility: The bottom is equipped with 4 360° rotating silent universal wheels (diameter 7.5cm), and the movement resistance is reduced by 60% when the load is 50kg.

Anti-rust treatment: The surface is electrostatically sprayed with epoxy resin, passed the 48-hour salt spray test, and the anti-rust level reaches ISO 9227 standard NSS 5 level.

Product features

1. Combination of high strength and light weight: The carbon steel frame weighs only 12kg, but its load-bearing performance is better than that of traditional wooden clothes drying racks (load-bearing increased by 200%).

2. Modular design: Supports free combination of 2-6 layers, and the single-layer expansion cost is reduced by 30%, meeting the needs of different scales.

3. Quick installation: No tools are required, and it can be unfolded or folded within 3 minutes, saving labor costs.

4. Environmental protection and energy saving: Replace dryers and reduce carbon emissions by about 120kg per year (calculated based on 2 hours of daily use).

Application areas

1. Family scenes

Small-sized drying racks: 8cm thick after folding, can be stored under the bed or in the corner, solving the problem of insufficient balcony space.

Drying of maternal and child products: The top layer has a spacing of 40cm, which is suitable for large items such as baby sheets and quilts, and is equipped with a detachable crossbar to achieve diapers and clothes drying in different areas.

Needs of a large family: The 4-layer structure can dry 30 adult clothes + 15 children's clothes at the same time, meeting the daily needs of a family of 5.

2. Commercial laundry room

Efficient turnover: 200kg of linens (such as hotel sheets and towels) can be processed per day, and with a mobile wheel set, the manual handling efficiency is increased by 50%.

Classification management: Different types of clothes are marked on each layer (such as light/dark colors, guest clothes/work clothes) to reduce the risk of mixed washing.

Cost control: Compared with fixed clothes drying racks, space utilization is increased by 70% and rental costs are reduced.

3. Industrial production

Air drying of electronic components: In the SMT patch workshop, it is used to air dry the PCB board after cleaning. The layer height of 30cm is designed to avoid component bumps, and the air drying efficiency is increased by 40%.

Food packaging disinfection: In the baking factory, it is used to dry trays and molds. The material meets FDA food grade standards and has a temperature resistance range of -20℃ to 120℃.

Rust prevention of hardware: In the electroplating workshop, it is used with a dehumidifier to shorten the drying time of the workpiece from 12 hours to 4 hours, and the production capacity is increased by 200%.

4. Medical institutions

Sterile items drying: In the operating room, it is used to dry the sterilized instrument package. The surface of the bracket is smooth and burr-free to avoid bacterial residue.

Management of patient gowns: Each layer is independently numbered, and with RFID tags, clothing tracking is achieved, and the loss rate is reduced by 90%.

5. Outdoor activities

Camping equipment drying: The volume after folding is 0.12m³, which can be put into the trunk of a car. The single layer bears 10kg, which is suitable for large equipment such as tents and sleeping bags.

Emergency rescue: At the post-disaster resettlement site, the clothes drying needs of 200 people can be met in a single day, and the bottom wheel group can adapt to muddy ground.

Care and maintenance guide

1. Daily cleaning

Use a damp cloth to wipe the surface stains, avoid using acidic cleaners (such as 84 disinfectant) to prevent the coating from falling off.

Check the lubrication of the hinge parts every month and add special metal grease (such as Lithium Grease NLGI 2).

2. Rust prevention

In a high humidity environment (humidity>80%), spray rust inhibitors (such as WD-40) every month, focusing on protecting welding points.

For long-term storage, it is recommended to disassemble and put them in a moisture-proof bag (humidity control<40%).

3. Repair and replacement

When the wheel wear exceeds 2mm, it needs to be replaced. It is recommended to use polyurethane rubber wheels (diameter 7.5cm, hardness 70 Shore A).

When the bracket deformation exceeds 5%, it needs to be scrapped to avoid safety hazards.

FAQs

Q1: Does the product support customized size?

A: Yes, the minimum order quantity is 100 units, and the length can be customized to 120-240cm, 2-8 layers, and the delivery time is 15-20 days.

Q2: How to solve the problem of jamming after folding?

A: Check whether there is any foreign matter stuck in the hinge part, and apply special grease; if the problem persists, contact after-sales to replace the hinge assembly (warranty period is 2 years).

Q3: Can it be used for special materials that cannot be handled by the dryer?

A: It can safely dry delicate fabrics such as wool and silk, but it needs to avoid long-term exposure to the sun (recommended temperature <50℃).

Q4: How to calculate the cost of large-scale procurement?

A: The unit price decreases with the purchase volume (100 units: 45/unit; 500 units: 38/unit; 1000 units: $32/unit), including sea freight (FOB Shanghai Port).

Q5: Is there an installation video?

A: Provide bilingual video tutorials in Chinese and English, and attach 3D disassembly diagrams, which customers can obtain through the official website or email.
