Thickened steel four-post dark gray single-sided wall-mounted supermarket shelving

Core Advantages

    Four‑post support structure: Four vertical posts (front and rear rows) distribute loads to multiple wall anchor points or the floor, reducing force concentration compared to two‑post designs.

    Thickened posts: Posts are made from cold‑rolled steel of increased gauge (exact thickness available upon request). The larger cross‑sectional moment of inertia improves bending stiffness, minimizing lateral deflection under full load.

    Shelf load capacity: Shelf brackets lock into the four posts at multiple points. Shelves feature edge bending and bottom stiffeners. Per‑shelf capacity meets the requirements of heavy items such as full beverage cases, 5L cooking oil bottles, and bagged rice.

    Wall‑mount installation: The back of the unit attaches to concrete or solid brick walls using expansion bolts. The number of connection points between the four posts and the wall exceeds that of two‑post units, enhancing overturning resistance.

    Space utilization: With a height of 2800mm, multiple tiers maximize vertical wall space. The 480mm depth occupies minimal aisle footprint.

    Customization: Overall dimensions, number and spacing of shelves, color, post and shelf thickness can be adjusted per order.

FAQ & Precautions

Frequently Asked Questions

    What is the difference between four‑post and conventional two‑post shelving?
    Standard single‑sided wall‑mounted shelves typically use two posts (front corners). The four‑post design adds two rear posts, distributing loads across four vertical support points. This improves lateral force resistance, making it suitable for tall, heavy products or frequent horizontal handling.

    What is the load capacity per shelf?
    Capacity depends on shelf thickness, stiffener count, and span (2400mm). Under typical thickened configurations with solid panels, each shelf supports 120‑150kg under uniform distribution. Request load test reports from the manufacturer.

    Is wall mounting mandatory?
    This product is designed for wall mounting to utilize wall support. If wall conditions are unsuitable, adjustable feet can be added to the bottom of the four posts to convert to a freestanding unit, provided the floor can bear the total load.

    Do scratches show easily on the dark gray powder coating?
    Darker surfaces show scratches less visibly than white surfaces. The coating hardness is consistent with standard powder coating. Avoid contact with sharp metal objects.

Precautions

    Before wall mounting, confirm the wall is concrete, solid brick, or masonry of sufficient strength. For lightweight partition walls (e.g., drywall, hollow brick), either reinforce the structure or use the floor‑standing configuration.

    Use expansion bolts appropriate for the wall type (M10 or M12 recommended). Bolt embedment depth and quantity must be calculated based on the fully loaded weight of the unit. All bolts must be tightened after installation.

    When stacking heavy items, distribute full cases evenly across the shelf surface. Avoid concentrating weight on one side.

    Periodically inspect bolts connecting posts to the wall and shelf bracket clips for loosening, especially in vibration‑prone environments.

    Clean the powder‑coated surface with a soft cloth and mild detergent. Do not use steel wool or strong acidic/alkaline solvents.
