Laidlaw Balustrades – The Components of the Systems

Handrails Components

Handrails are of nylon-sleeved galvanised steel tube, stainless steel or solid timber with nylon or stainless steel bends and support brackets. All handrails have a diameter of 40mm.

Stainless steel handrails brackets are of 14mm diameter bar. Nylon handrails brackets are of 34 or 40mm diameter nylon (complete with reinforced steel core). In the Combi system, the handrails can have a different material from that of the support bracket.

All handrails supports conform to the key dimensions in Approved Document M and the 2005 amendment to BS 8300, when fitted to a 40mm diameter handrails.

All handrails terminate by returning to the wall and finishing either with a fixing rose, or with a stop-end close to the wall.

Balustrades Components

Laidlaw Balustrades’ balustrades consist of the following components:

  • Top rails
  • Bottom rails (optional)
  • Uprights
  • Infill
  • Infill panel holders.

Top rails

Like handrails, the top rails of balustrades are of nylon, stainless steel or solid timber, with nylon or stainless steel bends and connections. All top rails have an outside diameter of 40mm. Nylon top rails have a 2mm thick corrosion-resistant galvanised steel core, except for the 3kN system where the core is 4mm thick. The 4mm nylon sleeve is durable, has a low conductivity and cannot be chipped, peeled or worn away.

Bottom rails

Bottom rails are usually of the same material as the uprights.

Uprights

Uprights are of nylon-sleeved galvanised steel or stainless steel, depending on the system options. They are generally of 40mm diameter tube, but of 60mm diameter tube for the ‘3kN’ system, which is designed to resist a greater horizontal load, e.g. in assembly buildings.

Connection to the top rail is either ‘in-line’, or ‘offset’. For the in-line connection, the 40mm upright meets the top rail with a ‘T’ connection. Alternatively, the upright can have a reduced diameter connection to the top rail to improve the easy movement of the hand along the rail.

Where the connection is offset, the top rail is supported by handrails-style brackets. Usually, where the top rail is offset, so are the bottom rail and the infill, although it is possible to have the infill on the opposite side of the upright to the top rail, or the infill in-line where an additional offset lower handrails is provided.

Infill

Balustrades infill is available in a three basic forms (see Product Selector):

  • Strained wire
  • Mid rails
  • Panels, using a variety of materials.

Strained wire or mid rails is always in-line, whereas infill panels can be either in-line or offset, depending on the way they are connected to the uprights. The options for each of the Laidlaw systems are shown in the Product Selector.

Infill panel holders

Panel holders are either of steel-reinforced nylon or stainless steel to match the uprights or the top rail. Most clients prefer a rounded design, but a square design is available, depending on the size of the contract.

In-line panels are connected to the uprights by ‘clamp’ type panel holders, offset panels by ‘screw-stud’ holders.

Clamp type panel holders have their Allen Key fixings either concealed or exposed. These panel holders can accept panels with a thickness up to 10mm when in stainless steel and up to 14mm when in nylon.

All offset screw-stud type holders can accept panels with a thickness up to 14mm, whether in nylon or stainless steel. The advantage of using offset panel holders is that toughened glass panels can continue past the uprights in lengths up to 3.5 metres, i.e. greater than the normal spacing of the uprights.
