and associated

engineering.”

“Their innovative

Hopleys, a division of Hunt Engineering

& Staff Pty. Ltd., has over 60 years

experience and a respected reputation

in Sheet Metal fabrication and

associated engineering.

Hopleys’ steady growth has been

based on mechanical and structural

engineering skills, backed up by first

class craftsmanship.

During the 1970’s when the building

and construction industries were

experiencing a rapid growth,

prefabrication suddenly became a

high growth opportunity. Faster, more

economical time saving components

were required on building and

construction sites.

Hopleys, the metal building products

division of Hunt Engineering identified

the opportunity for the development of a

light weight steel joist. The result of the

research and development was a unique

open web steel joist, made from light

weight, high grade steel, galvanised for

corrosion protection.

Having taken the decision to produce

and market joists, Hopleys set about

designing and building special rolling

and welding equipment and set up

production facilities.

Modern fasteners, such as self taping

screws, along with versatile tools were

by then readily available and widely

in use. These, together with specially

designed standard fittings greatly

enhanced the ease of installation.

Hopleys ® steel joists are manufactured 400mm & 450mm as well as ‘made

from light weight galvanised steel to order’ specials as requirements

for durability and require little or dictate, and are manufactured to any

no maintenance. Their obvious length required.

advantages over timber products are

They also offer easy man handling,

“Their open web design

permits ready access

services such as pipes

and cables.”

Flooring -

Commercial

& Industrial

Open Web Steel Joists offer unique

possibilities in both design and cost

effectiveness because of fast erection,

high rigidity and a no maintenance

finish.

Typical industrial applications include

mezzanine and multi-level flooring,

conveyor decks, catwalks, stages,

platforms, workrooms and storage

rooms.

Some typical commercial applications

include office mezzanines, raised

floors, showrooms, computer floors

and raised storage areas.

They offer a flat easy to mount surface,

with good load bearing characteristics

and high durability.

The open web design also allows

access for pass through services,

reducing the overall floor thickness.

The ‘HB’ Range can be doubled up,

when required, to provide structural

members which can be hidden

within the floor thickness, eliminating

unsightly bulkheads.

Domestic

“They offer a flat

surface, good load

bearing characteristics

and high durability.”

Hopleys ® light weight galvanised

open web joists are ideal for domestic

flooring applications. They are suitable

for both subfloor and particularly first

floor applications because of their light

weight and easy installation. They also

make fitting for pass through services,

such as electrical wiring and plumbing,

extremely easy. They offer a flat surface,

good load bearing characteristics and

high durability. Our light weight joists

reduce flooring dead loads which in

turn reduces the size of the supporting

members and lowers overall costs.

They allow larger spans, reducing stump

and bearer costs and installation time.

Roofing -

General

Although commonly referred to as a

joist, the HJ & HB range of products

are ideal for use as a truss or rafter in

all types of roofing.

Skillion or gable constructions are

suited to our joists for use in domestic,

industrial and agricultural areas. ie.

houses, carports, garages, factories,

farm sheds and lean-to’s.

They may also be used for hanging

beams and suspended ceilings.

are over multiple supports the spans may be increased. Consult your / our engineer for details.

Check with your/our

Engineer to determine

the appropriate design

loads for your floor.

"We use and

recommend

DuraGal ®

Adjustable

Stumps"

FLOOR SHEETING

We recommend the following minimum sheet flooring thickness:

1.5kPa Floor Load, Joists @ 450mm c/c

19mm Structaflor ‘Yellow Tongue’ Particleboard Flooring OR 17mm Plywood, F11

1.5kPa Floor Load, Joists @ 600mm c/c

22mm Structaflor ‘Red Tongue’ Particleboard Flooring OR 17mm Plywood, F14

3.0kPa Floor Load, Joists @ 450mm c/c

22mm Structaflor ‘Red Tongue’ Particleboard Flooring OR 17mm Plywood, F14

3.0kPa Floor Load, Joists @ 600mm c/c

25mm Structaflor ‘Blue Tongue’ Heavy Duty Particleboard Flooring OR 19mm Plywood, F14

5.0kPa Floor Load, Joists @ 450mm c/c

25mm Structaflor ‘Blue Tongue’ Heavy Duty Particleboard Flooring OR 19mm Plywood, F14

5.0kPa Floor Load, Joists @ 600mm c/c

25mm Structaflor ‘Blue Tongue’ Heavy Duty Particleboard Flooring OR 21mm Plywood, F14

An approved construction grade adhesive should be used to bond the sheet flooring

to the joists. Approximately 2 tubes of 850ml will be required per 10 - 3600mm x

900mm sheets.

FLOOR PERFORMANCE

Steel framed floors are generally stronger, lighter and have less deflection than a

conventionally framed timber floor. They offer many benefits including savings in

costs, installation time and dead loads. Steel framed floors also react differently to

applied loads than a timber floor. This dramatic increase in dynamic performance

and without the effects of creep, rot and termites, will see your steel floor deflect the

same amount after 20 years as it did when completed.

Our span tables have been designed to keep the deflection below the level required

by the Building Code of Australia.

When using Hopleys Joists to create large open areas such as family or rumpus

rooms, please consult your Hopleys ® representative.

SPACING AND SPAN

“Spacing” is the centre to

centre distance between

structural members and

is assumed to be 450mm

unless noted otherwise.

“Span” is the face to face

distance between points of

support for the structural

members.

“Single Span” is the span of a

member supported at both ends with no

intermediate support. This is also known as

“simply supported”.

“Continuous Span” is when a member has support at both

ends and also at one or more evenly spaced points between the ends.


9

Extra joists should be added under

non load bearing, internal partition

walls which are within 80% of their

maximum span.

Add extra joists at half spacing under

spa baths or water beds.

For all load bearing internal walls or

point loads, please consult with your

Hopleys representative.

Do not notch top or bottom chords

or remove webs. If a web needs to

be removed, please consult with your

Hopleys representative.

We highly recommend screwing

the sheets to the joists using a

QuikDrive PRO250 Auto-Feed

Screw Driving System, which can be

purchased or hired from your Hopleys

representative. You will require

approximately 29 screws per 3600mm

x 900mm sheet.

Alternatively the floor sheets can be

nailed down using hardened twist nails

available from various manufacturers

such as Senco, Duo-Fast, Bostitch and

Paslode.

Ensure that once the floor has been

fixed that any nails protruding through

and touching the webs are bent away

a few millimetres using pliers.

When using standard framing guns to install your sheet flooring, ensure

hardened twist nails are used as per your gun manufacturers instructions.

Hopleys ® are ready to solve all the

Special

Applications

The Hopleys ® joists have also been

design criteria of your projects using used for permanent and temporary

their Computer Assisted Design grandstands, exhibition structures and

techniques with their in house

for opera and theatre staging.

Engineers and Design Draftsmen.

The many advantages offered by open

web steel joists allow you to form the

most complex construction shapes

while improving on site work speed

and cost effective construction.

Hopleys ® joists are often used in place

of heavier and larger structural steel

sections originally specified. Savings

are made in both installation and

material costs.

Hopleys ® open web light weight steel

joists are an economical solution for

portal frames. Typical applications

include farm sheds, machine and hay

sheds, horse sheds, garages and

carports.

Additional to our Standard range, Hopleys can also

design and manufacture customised Large Span

Trusses to suit your specific application in a range of

widths and depths.

Hopleys large span beams generally feature DuraGal

rectangular hollow sections, which means extra strength

and superior corrosion protection.
