Mechanical Anchoring solutions in New Zealand

Choosing the right mechanical anchor for your project:

Selecting the right concrete tools or bolt for anchoring is more than just choosing a size. Key factors to consider include:

• Load and substrate: What is the size and type of load it must support? Are you anchoring into concrete, brick, block or something else? Each anchor category is tested for specific capacities, and you want an engineering bolt solution that not only supports the load today but remains secure over time, especially in New Zealand’s harsh weather and climate.
• Environmental conditions: structures in coastal or high-moisture areas, for example, are subject to accelerated corrosion, so it’s important to choose corrosion resistant anchors such as stainless steel or coated anchors. In areas with wildly fluctuating temperatures anchors can also be subject to expansion/contraction stress.

When to use light-duty anchors

Light duty anchors such as WallMate™ mini anchors are designed for low-load residential, commercial and industrial applications where you’re fastening everyday items that involve quick installation with low force on the anchor. Typical uses include hanging small fixtures and fittings, and fixing shelving, light signage or trim.

Medium duty anchor applications

As the name suggests, medium duty anchors offer higher load capacity than light duty and are used for securing brackets or frames, installing handrails and anchoring timber or light steel to concrete or brick. Our anchor bolt range includes the DynaBolt™ Plus Sleeve Anchor for medium duty anchoring of timber and steel fixtures to concrete, brick or block. Sleeve anchors are effective in tightening and securing the anchor into place against the sides of the drilled hole with its integrated pull-down fixture.

When to use heavy duty anchors

Heavy duty anchors are engineered for high load, critical, or structural applications. These anchor bolts, such as AnkaScrew™ Xtrem™ support high tension and loads and are typically used for things like structural steel, machinery bases and other demanding NZ construction jobs.

What fastener should I use for concrete in NZ?

The Ramset heavy duty anchor range offers concrete tools and anchor bolts that NZ professionals trust for structural and non-structural concrete fixing. As a trusted fastening system that’s been product tested for NZ conditions, they are engineered to handle high tension loads, heavy and dynamic fixings, and seismic conditions.

Here are various concrete fasteners suited to different applications:

• For seismic-certified heavy-duty anchoring: TruBolt™ Xtrem™ and AnkaScrew™ Xtrem™
• For close to edge fixings: AnkaScrew™ Xtrem™
• For tension bracing: AnkaScrew™ Xtrem™
• For handling static loads and moving or vibrating loads: SpaTec™ Xtrem™ is ideal for cracked and non-cracked concrete fixing as well as seismic applications.
• For strong anchoring cast-in performance: Boa™ Coil Expansion Anchors Hex Bolt clamps and expands with the option for clean removal.

These concrete anchors and bolts provide fast, durable installation and are engineered for a wide range of demanding structural and support applications.
