Cullen is the market leader of timber engineering connectors within the UK and Ireland, currently holding 85% of the timber frame market, 55% of the roof truss and engineered floors markets. Our experienced Research and Development Team develop 10 cutting-edge products every year. This is why Cullen is the number one choice for timber connectors.
Our connectors
Cullen Building Products manufacture a range of timber engineering connectors for the following applications:
Timber to masonry connections
Timber frame connections
Engineered wood product (EWP) connections including products for all I-joist and open web system manufacturers
Solid timber & roof truss connections
Truss to wallplate connection including high load applications
Multiple connections for floors and roofs
Restraint straps for masonry and timber frame connections
Ancillary products
Custom connectors
Cullen are specialists in the design, development & manufacture of special connectors, and products to assist with disproportionate collapse in multi-storey timber frame buildings. Corrosion protection to the mild steel is by galvanising to Z275 & Z600. Timber frame wall ties and holding down straps are manufactured with austenitic stainless steel and supplied with the required fixings. Cullen products carry BBA certification and European Technical Approvals.

This part of ISO 22965 applies to concrete for structures cast in situ, pre-cast structures and structural pre-cast products for buildings and civil engineering structures. The concrete can be mixed on site, ready-mixed concrete or produced in a plant for pre-cast concrete products.
This part of ISO 22965 applies to concrete compacted to retain no appreciable amount of entrapped air other than entrained air and to normal-weight, heavy-weight and light-weight concrete. Other International Standards for specific products, e.g. pre-cast products, or for processes within the field of the scope of this standard can require or permit deviations from this part of ISO 22965. This part of ISO 22965 specifies the properties of constituent materials, the production of concrete and the compliance system of concrete.
This part of ISO 22965 does not apply to:
⎯ concrete with a maximum aggregate size equal to or less than 4 mm or 5 mm (mortar),
⎯ aerated concrete,
⎯ foamed concrete,
⎯ concrete with an open structure (“no-fine aggregate” concrete),
⎯ concrete with a density less than 800 kg/m3,
⎯ refractory concrete.
This part of ISO 22965 does not cover health and safety requirements for the protection of workers during production and delivery of concrete.

This publication provides a Worked Example for the design of a single-span fully integral bridge, that utilises High Modulus Pile abutments and a composite plate girder deck. It has been based on the findings of studies undertaken on steel integral bridges and steel substructures by The Steel Construction Institute since 1993.
Calculations are provided for each design stage, together with a detailed commentary explaining the background to the methods employed and the parameters chosen. Computer-based numerical techniques have been used to enable full soil-structure interaction to be considered in the analysis. A design is proposed for a reinforced concrete capping beam to provide a full moment connection between the High Modulus Piles and the deck.

I have Canon iR2018 connected on my work network.
Can I scan a multiple page documents (eg. books) and transfer the scanned file(s) to a network connected PC?
The material in this guide has been prepared as a reference of fire and sound rated lightweight steel framed assemblies. While every effort has been taken to ensure that the material is technically correct, it only offers a brief description of the tested assemblies. It must not be used without first reviewing the source documents of the testing agencies for a full description of the assembly. The Steel Framing Alliance, nor their organization’s members, warrant or assume liability for the suitability of the material for any general or particular use.
Please note that some assemblies are constructed with proprietary products that may not be available in all geographical areas. Please consult the source documents of the testing agencies for these details. Where fire rated designs utilize a proprietary steel joist, fluted unit, light gauge steel truss or steel stud, the source column appears shaded and the word proprietary is in bold font to allow ease of identification for an assembly built with a proprietary cold formed steel product.
The purpose of this guide is to amalgamate fire and sound data for steel floor, wall and roof assemblies that are relevant to residential and light commercial construction.

The provisions of this publication apply to the construction of detached one- and two-family dwellings, townhouses, and other attached single-family dwellings in compliance with the general limitations of Table 2.1. The limitations are intended to define the appropriate use of this publication for most one- and two-family dwellings. The provisions of this document can be used for framing elements or components that meet the applicability limits of Table 2.1 but located in buildings that do not meet all the requirements of Table 2.1 provided that the nonconforming limits do not impact such framing element or component. The provisions of this document can also be extended to buildings and components of buildings that do not meet the applicability of Table 2.1 and for other types of buildings (other than residential buildings) provided that each provision is carefully reviewed by competent individual(s) to ensure its applicability. Using cold-formed steel and wood components with other construction materials in a single structure shall be in accordance with the applicable building code requirements for that material, the general limitations of Table 2.1, and the relevant provisions of this publication. An approved design shall be required for applications that do not meet the limitations of Table 2.1.
