Made from galvanized steel, these U-shaped pins feature sharpened ends for easy insertion and firm grip across a range of soil types. With a U-width of 30mm and steel thickness of 3.15mm, they provide excellent holding power while resisting corrosion and rust even in harsh outdoor conditions.

    Available in three lengths—150mm, 200mm, and 300mm—our pins are suitable for both soft and compacted soils. Supplied in boxes of 500, they’re perfect for large-scale landscaping, construction, and civil works projects.

    Need help choosing the right pin length?
    Shorter pins (150mm) are best for firm, dense soil conditions, while longer lengths (200mm or 300mm) offer greater anchorage in loose or sandy soils.

    Installation Made Simple
    Just position your mat, mesh, or log and push the pin down until it sits flush with the surface. No tools required in most cases. For tougher ground, a mallet may help with easier placement.

    FAQs About Retaining Pins / Weed Mat Pins

    Retaining pins, also known as landscape staples or ground anchors, are primarily used to secure materials like erosion control blankets, weed mats, coir logs, and geotextile fabrics to the ground. Their U-shaped design ensures stability, preventing materials from shifting due to wind, water flow, or foot traffic.

    Retaining pins commonly come in lengths of 150mm, 200mm, and 300mm. The appropriate size depends on soil conditions:

    • 150mm: Suitable for hard or compacted soils.

    • 200mm: Ideal for medium-density soils.

    • 300mm: Best for loose or sandy soils where deeper anchoring is necessary.

    The standard U-width is typically around 30mm, providing a secure grip on the material being anchored.

    The number of pins required depends on the material and installation area:

    • For erosion control blankets or weed mats, it's recommended to place pins every 0.5 to 1 meter along the edges and at overlaps.

    • Allow for additional pins at overlaps and seams to ensure stability.

    For example, for a 10-meter-long blanket, you might need approximately 20 to 40 pins, depending on the spacing and site conditions.

    Yes, if the pins are made from durable materials like galvanized steel and are not bent or damaged during removal, they can be reused. However, repeated use may dull the sharp ends, making insertion into the ground more difficult over time.

    Retaining pins are versatile and can be used in various soil types. However, their effectiveness depends on the soil's density:

    • In hard or compacted soils, shorter pins (150mm) are effective.

    • In loose or sandy soils, longer pins (300mm) provide better anchoring.

    For extremely rocky or challenging terrains, specialized anchoring solutions may be more appropriate.

     

    In softer soils, retaining pins can often be inserted by hand. For harder or compacted soils, using a rubber mallet can help drive the pins into the ground more easily and ensure they are flush with the surface.

    Yes, galvanized retaining pins are coated to resist rust and corrosion, making them more durable and suitable for long-term outdoor use. Non-galvanized pins may corrode over time, especially in moist environments, reducing their effectiveness and lifespan.

    Absolutely. Retaining pins are commonly used to secure artificial turf, ensuring it stays in place and maintains a smooth, even surface. They help prevent movement due to foot traffic or environmental factors.

    If the pins are still in good condition, consider reusing them for future projects. If disposal is necessary, check with local recycling programs to see if they accept metal items. Avoid leaving pins in the ground, as they can pose hazards to people and equipment.
