Lindapter Façades & Cladding

Whether securing precast concrete panels, glazing frames, GRC cladding or other architectural façades, Lindapter has a proven connection solutions

Established in 1934, Lindapter International is the world’s pioneer of steelwork clamping systems, eliminating the need to drill or weld steel on-site. Lindapter connections can be temporary or permanent, adjusted on-site and do not damage steelwork; ideal for fixing elements of a building exterior to the structural steel frame.

This blog provides examples of cladding fixing assemblies, designed for permanent applications.

Lindapter offers a comprehensive design and support service to tailor its products to your specific application.

Structural Steel Frames

Hot rolled structural sections are manufactured with inevitable variations in exact dimensions, while steel erection techniques will create unavoidable tolerances in straightness along beam length and other dimensions.

Accurate adjustability during installation is therefore an essential prerequisite of the cladding support system.

Lindapter facilitates this requirement by allowing the cladding contractor to simply slide the bracket or other fixing assembly along a vertical or horizontal structural beam with precise alignment, before tightening the Lindapter components with a torque wrench. This method enables the rapid installation of large areas of cladding and significantly reduces the period of crane operation.

The following pages provide examples of connecting façade panels to structural sections. The illustrations highlight the many possibilities of securing panel brackets and threaded bar fixing assemblies.

Structural Hollow Section

Square / rectangular Structural Hollow Section (SHS) is a popular material amongst architects, with many contemporary designs making a feature of exposed structural steel profiles to enhance the aesthetics of a building.

Responding to industry demand for a faster alternative to welding or through-bolting, Lindapter invented the Hollo-Bolt®; a structural expansion bolt specifically designed for primary or secondary SHS connections.

The Hollo-Bolt’s discreet profile is particularly well suited to external or internal glazing support frames.

Installation is carried out quickly and safely by inserting the product into pre-drilled holes and tightening to the recommended torque using simple hand tools.

This section of the brochure provides examples of cost efficient methods of connecting façade panels and curtain walls to SHS. The Hollo-Bolt can be used in a wide range of primary or secondary connections, including specialist applications such as blast resistance cladding.

The entire Hollo-Bolt range has achieved CE mark certification, independently verifying product performance in safety critical applications.

Steel to Steel Connections

Behind a structure’s façade, there is often a supporting steel framework. Lindapter Girder Clamps provide a faster alternative to traditional connection methods, compatible with almost any shape and size of section, in a wide variety of applications.

The Girder Clamp symbolises Lindapter’s philosophy perfectly; boldly challenging the need to drill or weld, when a safe, high strength connection can be quickly accomplished by clamping two steel sections together 

Although the concept is simple, Lindapter products undergo complex design and testing as the experienced Research & Development team constantly refine, improve and invent to achieve greater product performance, verified by independent product approvals.

Lindapter Girder Clamp configurations using Type A and B products are CE Mark approved.

Project Experience

St David’s Shopping Centre, Cardiff, UK

Consulting Engineers on this £675m retail project invited Lindapter to design a bespoke adjustable connection system to facilitate the accurate positioning of a sandstone faced façade. Lindapter’s proposed solution comprised a steel bracket with slotted holes that could be clamped to the structural members with Type LR clamps.

Military History Museum, Dresden, Germany

Lindapter Hollo-Bolt fixings secured perforated steel cladding panels to the structural steel hollow section in Daniel Libeskind’s impressive five storey façade. The arrow shaped extension, made from glass, concrete and steel, intersects the original neo-classical arsenal building. The arrow’s steel cladding was secured using over 2,000 M8 stainless steel Hollo-Bolts.

Lindapter’s patented Hollo-Bolts provided the contractors with a connection solution that could be easily installed from just one side, avoiding welding and on-site drilling.

The discreet Hollo-Bolts were manufactured from Grade 316 stainless steel for enhanced corrosion resistance.

St Pancras Station, London, UK

In the most crucial part of the refurbishment of the Grade 1 listed ‘Barlow Shed’ at St Pancras Station, the Type AF clamp allowed a new steel framed roof to be connected to the Victorian arches without any damage to the original steel sections.

Lindapter’s connection solution also provided height adjustability and the ability to be moved up and down the beams to optimise alignment.

The Type AF clamp’s high resistance to frictional loads ensured a secure connection at all angles of the arched beams.
