Climbing Net

A climbing net is a high-strength polyester net hung as a surface to climb on, not as a barrier to fall against. It goes on playground frames, in climbing halls, over obstacle courses, on school walls and on the A-frames that parks buy as a single item. It is light for its strength, it is tensioned rather than draped, and the mesh is a safety decision before it is a design one.

That last point is the difference between this page and the other nets in the catalogue. A cargo net is judged by what it holds; a climbing net is judged by what it lets through, how it feels under a hand and a shoe, and whether it is still tight after a season of children hanging off the same square metre.

A surface, not a barrier

Three things change when a net is climbed rather than hung in front of cargo, and all three have to be in the specification from the start.

• It is loaded sideways and in shear. A body on a net pushes it out of plane, so the lacing carries the load into the frame along its whole edge rather than at four corners.
• The mesh is gripped. Hands and shoes go into the openings, so the mesh size is set by what a foot and a hand can use – and by what a head cannot pass through.
• It is loaded by people who do not think about loads. A playground net takes repeated dynamic load from children who jump, swing and hang two to a square. A static figure on a drawing is not the design case.

The mesh is the safety decision

Every conversation about a climbing net arrives at the mesh size, and the answer is not a preference. Two constraints pull in opposite directions: the openings have to be big enough for a foot and a hand, and small enough that a head cannot pass through and be held.

Play equipment standards treat an opening of roughly 89 mm ke 230 mm as a head-entrapment risk, which is why playground nets are normally specified with a mesh below that band – 45 to 60 mm is the usual range for a net children climb. Training nets for adults go coarser, 100 to 150 mm, because the grip is bigger and the head is not.

Lacing is the fixing

A climbing net is not bolted to a frame; it is laced to it. A cord or a narrow strap passes through the border and around the tube every 150 to 300 mm, and the tension is set by how hard that lacing is pulled – which is why the border and the lacing, not the mesh, decide whether a net feels like a trampoline or a hammock.

• Spacing. 150 – 200 mm on a play net, 250 – 300 mm on a large training panel. Even spacing matters more than tight spacing.
• Corners. A thimble or a protected eye at each corner; the corner is where a net tears first.
• Tension. Tight enough that the net does not bottom out against the frame when someone stands on it, and not so tight that the frame is pulled out of square.
• Accessories. A tensioning cord with a cleat, or a strap and buckle, lets a net be re-tensioned after a season without re-lacing the whole edge.

Loads, and what nobody should assume

A climbing net is not a lifting sling and it is not a fall-arrest net, and it carries no working load limit. What it carries is people, dynamically, in numbers nobody controls – two children on one square, an adult pulling themselves up by the border, a group at the top of an A-frame at once.

So the figures come from outside the net: from the play standard the site is built to, or from the engineer who designed the frame. What this works supplies is the net made to that brief – rope or webbing, mesh, border, lacing points and colour – and the frame design stays with whoever signs for the structure. Where a project needs a documented figure for the net itself, say so on the enquiry and it is quoted before the order.

Shapes and frames

• A-frame. The park and school standard: a net over a steel or timber A, climbed from both sides, usually with a horizontal section at the top.
• Wall panel. A flat net on a wall or a facade, framed or laced to anchors, for climbing halls and feature walls.
• Overhead and tunnel. A net slung between two frames as a crawl or a bridge, tensioned along both edges.
• Wall overlay. A net fixed over a climbing wall to add routes, or over a plain wall to create one.
• Tree and garden. A small net between two trees or on a timber frame, for domestic use.

Indoors or outdoors

Polyester is the default outdoors: it takes UV better than nylon, holds colour longer and does not go slack in the rain the way a nylon net does. Nylon is softer in the hand and is often chosen for indoor halls, where the light is kind and the net is not asked to survive a decade of sun.

Colour is a specification, not a decoration: a bright net is visible against a dark frame and reads as play equipment, and a colour that fades in two summers is the most common complaint on an outdoor installation. Say which colour and whether it has to match something that already exists.

Pemeriksaan, and what retires a net

• Wear at the lacing points, which is where a net works hardest and where a strand first goes thin.
• A cut or a UV-stiffened strand – a faded net that has gone stiff has lost strength before it looks worn out.
• Knots that have worked loose, or a splice that has started to draw.
• A border that has slipped in its stitching at a corner.
• Anything that will not tension any more: a net that has stretched beyond its lacing cannot be made safe by pulling harder.

Where the rest of the detail lives

The neighbouring nets, and the two products most often confused with this one, are on their own pages.

• Safety rope net – the category, including fall-protection nets
• Container cargo net – the barrier at a container door
• Staircase safety net – the domestic version of the same idea
• Jaring pengangkat kargo – the rated net that carries a load in the air
• Nylon rope – the rope in the net, and the climbing rope
• Safety harness – for the people who work at height, not for play
