Light Duty Height-Adjustable Storage Rack (90-190kg/Level) 4-Tier for Craft Studio Material & Tool Storage

- Material: Q195 cold-rolled steel (shelf panel: 1.2-1.5mm thick; frame column: 1.8-2.0mm thick, 25×25mm square tube)

- Load-Bearing Capacity: 90-190kg per level (evenly distributed); total rack load: 360-760kg

- Tier Quantity: Standard 4 tiers; adjustable to 3-5 tiers

- Height Adjustment: Stepless adjustment at 25mm intervals; total height range: 1200-1800mm (standard: 1500mm); single-tier height adjustable: 150-400mm

- Shelf Size: Standard width×depth: 900×450mm / 1200×500mm (fits craft studio workbenches)

- Surface Treatment: Electrostatic powder coating (epoxy resin, thickness ≥ 60μm); color options: white, gray, light blue (scratch-resistant, easy to clean); salt spray test resistance: ≥ 200 hours

- Assembly: Boltless snap-on design; no professional tools required

1. Flexible Height Adjustment for Craft Supplies: Stepless 25mm interval adjustment adapts to materials of all sizes—e.g., 150mm height for small paint tubes, 400mm height for 30cm fabric rolls, solving the problem of "too tall for fixed racks, too short for space waste."

2. Sturdy & Delicate Material Protection: Q195 steel frame with reinforced shelf edges (rounded, radius ≥ 2mm) avoids scratching delicate materials like hand-dyed yarns or paper crafts; powder-coated surface is non-toxic (meets REACH standards) and resistant to paint/stain spills (wiped clean with a damp cloth).

3. Space-Saving 4-Tier Design: 4 tiers maximize vertical storage in compact craft studios (10㎡ studio can store 50+ types of supplies vs. 20+ with single-layer storage); narrow depth (450-500mm) fits against studio walls, leaving more floor space for crafting tables.

4. Tool-Free Quick Assembly: Boltless snap-on structure—2 people can assemble the rack in 20-30 minutes (includes detailed instruction manual with diagrams); easy to disassemble and rearrange if the studio layout changes.

5. Multi-Scene Craft Adaptability: Suitable for various craft types—sewing (stores fabrics, threads, scissors), pottery (stores clay blocks, sculpting tools), painting (stores paints, brushes, canvases), and woodworking (stores small lumber, sandpaper rolls); per-level load of 190kg supports heavy craft materials like 10kg ceramic clay blocks.

1. Steel Cutting & Forming: CNC shearing machine (accuracy error ≤ 0.3mm) cuts steel plates into shelf panels and frame columns; hydraulic bending machine shapes columns into square tubes (25×25mm) with uniform dimensions.

2. Shelf Reinforcement: Shelf panels are stamped with reinforcing ribs (spacing: 100mm) to prevent sagging under 190kg load; edge rolling treatment (thickness doubled) enhances durability and safety.

3. Surface Treatment: - Pretreatment: 3-stage cleaning (degreasing → derusting → phosphating) to remove impurities from the steel surface, ensuring coating adhesion. - Powder Coating: Electrostatic spraying of epoxy resin powder, followed by baking at 180-200℃ for 25 minutes—forms a smooth, even coating with no bubbles or pinholes.

4. Accessory Production: Adjustable shelf brackets are made of high-strength plastic + steel inserts (load-bearing ≥ 200kg per bracket); snap-on latches are tested 500 times to ensure no loosening after assembly.

5. Finished Product Testing: - Load Test: 1.2× rated load (228kg/level) applied for 24 hours—no permanent deformation or bracket disengagement. - Adjustment Test: 50 times of height modification—brackets slide smoothly, no stuck or damage. - Impact Test: 1kg craft tool (e.g., scissors) dropped onto the shelf—no coating peeling or panel deformation.

1. Sewing & Textile Studios: Stores fabric rolls (cotton, linen), spools of thread, sewing machines (small portable models), scissors, and ironing accessories; adjustable height fits 10-30cm fabric rolls.

2. Pottery & Ceramic Studios: Stores ceramic clay blocks (10-15kg each), sculpting tools (clay knives, molds), unfired pottery blanks (on soft padding), and glazes (in sealed containers); sturdy structure supports heavy clay loads.

3. Painting & Art Studios: Stores acrylic/oil paints (tubes/jars), paintbrushes (in holders), canvases (small-medium sizes), easels (foldable), and drawing paper rolls; powder-coated surface resists paint splatters.

4. Woodworking & Handicraft Studios: Stores small lumber pieces (2×4ft), sandpaper rolls, carving tools, glue bottles, and finished wooden crafts; rounded edges prevent scratches on wood surfaces.

5. DIY & Hobby Studios: Multi-purpose storage for scrapbooking supplies (paper, stickers), jewelry-making materials (beads, wires), and model-building kits; adjustable tiers keep small items organized and visible.

1. Size & Tier Customization:

- Shelf Dimensions: Custom width (600-1500mm) and depth (300-600mm)—e.g., 600×300mm for narrow studio corners, 1500×600mm for large-scale craft supply storage.

- Tier Quantity: Adjust to 3 tiers (for low-ceiling studios) or 5 tiers (for high-ceiling spaces); 5-tier racks have a maximum total load of 950kg (190kg/level).

- Height Range: Extend total height to 2000mm (for tall craft materials like 1.8m canvas rolls) or reduce to 1000mm (for children’s craft studios).

2. Function Customization:

- Partition Installation: Add detachable steel partitions (height: 100-200mm) on shelves to divide small supplies—e.g., separating different colors of thread or paint tubes.

- Hook Bars: Install metal hook bars on the side of the rack to hang tools like scissors, paintbrushes, or measuring tapes (saves shelf space).

- Label Holders: Attach plastic label holders (clear, 5×10cm) to shelf edges for quick supply identification (e.g., "Red Paint," "Cotton Fabric").

3. Appearance Customization:

- Color Matching: Offer custom powder coating colors (e.g., pastel pink for jewelry studios, natural wood-tone for woodworking studios) to fit the studio’s aesthetic style.

- Logo/Pattern Printing: Print studio logos, craft-themed patterns (e.g., paintbrushes, sewing needles) on frame columns (silk-screen printing, wear-resistant).

4. MOQ & Lead Time: Minimum order quantity for customization: 5 units; design confirmation takes 1-2 working days; production lead time: 7-10 working days (includes assembly accessory packaging).
