Purlin Division – Who are we?

• voestalpine Metsec plc is the UK’s largest designer and manufacturer of light gauge galvanised steel purlins, side rails and mezzanine floor systems producing approx. 25,000 tonnes / year.

• Our systems have been developed over the years with full scale testing and component testing at the University of Strathclyde. This combined with various theoretical approaches, first and second order theories and finite element analysis have resulted in us having the most efficient system in the market.

• Our Cold rolled steel purlins are manufactured from hot-dipped galvanised steel to BS EN 10346:2015 with a yield strength of 450N/mm2 and with a Z275 coating containing 275g/m2 of zinc. This material in combination with our systems and testing gives a competitive lightweight solution.

Purlin Division

• Our material is checked by our quality department to ensure that the chemical and mechanical properties on the mill certificate comply with BS EN 10346 and checks are also done on thickness and galvanised coating

Advantages of Light Gauge Steel

• Cost effective in comparison to heavier hot rolled steel angle and channel profiles

• High strength to weight ratio

• Designed as a system

• Long spans (up to 15m)

• Pre-galvanised sections give a longer term durability

• Material is delivered to site pre-punched and cut to length

• Lightweight, easy to handle and construct

• Recyclable, steel is 100% recyclable

Roof Systems

• 3 different types of system

• 45 different Zed Purlins in various depths and thickness ranging from 142-402mm deep optimised for performance

Roof Systems - Butt Purlin System

• Used on buildings with uneven bays

• Can be used for both inset and oversail applications

• Spans up to 15m

Roof Systems - Sleeved Purlin System

• Used on buildings with 2 bays or more

• Continuous system over 2 equal bays

• Spans up to 15m

Roof Systems –Heavy End Bay Sleeved Purlin System

• Most economic solution

• Continuous system used on buildings with 5 equal bays or more

• Heavier gauge purlins and sleeves are fitted in the end bays with lighter gauge purlins fitted on the internal bays

• Spans up to 15m

Roof Systems – Eaves Beams

• 7 Different eaves beams in various depths and thickness

• Used to support a rainwater gutter and the interface between the roof and wall cladding

• Counterformed web holes and packing plates used to provide an unobstructed side sheeting face

Side Rail Systems

• 2 different types of system

• 82 different Zed Purlins and C-sections in various depths and thickness ranging from 142-402mm deep

Side Rail Systems –Butt Side Rail System

• Used with both Z and C-sections for vertical and horizontal cladding

• Used on buildings with uneven bays

• Can be used for both inset and oversail applications

• Spans up to 15m

Side Rail Systems –Sleeved Side Rail System

• Used with both Z and C-sections for vertical and horizontal cladding

• Most economic solution

• Used on buildings with 2 bays or more

• Continuous system over 2 equal bays

• Spans up to 15m

Roof Systems – Sleeves

• Sleeves are used over the supports to provide a continuous purlin system

• The purlin shape is manufactured in such a way that the purlin will nest when turned upside down. A sleeve is therefore a short length of section

Roof Systems – Sag Rods

• Sag rods are used to restrain the bottom flange of the purlin under the wind uplift condition

• On 142-262mm deep purlins the round-lok type anti sag rods are used

SAG ROD

Side Rail Systems – Side Rail Supports

• Bolted between the lines of side rails to provide restraint to the inner flange of the rail and prevent rotation

• Used in conjunction with diagonal tie wires to transfer cladding weight to the columns

Side Rail Systems – Diagonal Tie Wires

• Used in conjunction with the side rail supports the diagonal tie wires are fixed between the bottom two rails and bolted to the cleat hole nearest the column face

• Supplied fully assembled with adjustable ends for easy erection

Side Rail Systems –Panel Joint Rail (PJR)

• Provides support to horizontal cladding panels at joint positions

• Adjustment provided by slotted holes in the fixing cleats

• To be used in conjunction with C-section rails to obtain maximum adjustment

• Diagonal tie wires are fixed between rails similar to when using side rail supports

Side Rail Systems –Horizontal Cladding Support (HCS)

• Provides intermediate support to horizontal cladding panels

• Adjustment provided by slotted holes in the fixing cleats

• To be used in conjunction with C-section rails to obtain maximum adjustment

• Diagonal tie wires are fixed between rails similar to when using side rail supports

Purlin Detailing within Tekla

• Complete product library available

• Streamlined macros speeding up the detailing process

• Eliminates errors – Saving time and money

• Manufacturing details can then be easily extracted and transferred electronically, and our software and experienced detailers will check this information and flag any issues back to the customer

Middle East Case Studies

Midfield Terminal Abu Dhabi

• Designed by Arup Cardiff Office using MetSPEC

• Butt System utilized

Midfield Terminal Abu Dhabi

• Designed by Aecom Abu Dhabi using MetSPEC

• 10.5 meter clear span sections

Nakilat Damen Shipyards

• 15 metre clear span sections

• Part of Metsec’s design offering was undertaking the structural calculations for the project

• Originally designed using Metsec’s heavy end bay system, with the 342Z25 section in the end bays and the 342Z23 in the internal bays

• Metsec team value engineered the project, designing a bespoke 342Z20 section for the internal bays, and the 342Z30 section for the end bays. This value engineering resulted in a 15% reduction in the weight of the roof, giving the client a more cost effective solution

• Over 1000 tons of purlins supplied over 12 months

CPD Design Guide for Steel Framing Systems

Overview

• Stud size, spacing and anchorage are determined by floor-to-floor heights, structural openings and lateral wind pressures

• Higher capacity of sections allows for more efficient design

• Wider flanges allow for minimum edge fixing for boarding

A lightweight fast track building method that provides the flexibility to fix virtually any façade and internal finish

Infill Walling

• Allows the SFS to be installed from the inside of the building

• Typically the most economical SFS solution

• Parapets and downstands can readily be formed with SFS using Metsec’scantilever posts

• Deflection built into design using Metsec’s unique slotted head track

Constructed within the primary structure from the floor to soffit of the primary structural frame to ‘infill’ the external wall zone

Continuous Walling

• Allows for curved wall design

• Easily achieves parapet

• Ideal where movement joints in the external cladding need to be minimized

• Studs are fixed to each slab edge using slotted cleats to allow for vertical movement in the primary structure

SFS ‘oversails’ the edge of the primary structure to maximise floor area

High Bay Separating Walls

• Can be constructed up to 20m high

• Rarely any need to provide additional foundations underneath the wall

• Up to 3 hrs fire protection

• No need for expensive hot rolled steel wind posts

• Allows for greater deflection

Internal wall used to provide high separating walls for factory units or atriums

Timber Cladding

Typically 2 layers of plasterboard to inside face

Studs, typically at 600mm centres

Insulation between studs

Sheathing board fixed to studs

Timber battens and helping handbrackets are fixed to the studs

Ventilated Rainscreen

SFS vs Blockwork

• SFS requires up to 25x less lorry deliveries to site

• SFS is much quicker to build

• In a typical week, with two teams of three installers, SFS can offer 124m2 greater coverage than blockwork, with 4 teams of brick layers

• Allows a rapid dry envelope

• Even with conservative data, SFS would reduce the installation programme by three weeks

SFS offers a number of benefits when compared to blockwork as a build method
