What is hardware?

Metal products used in construction Fixtures, equipment, tools used for general

purpose construction and repair of a

structure or object.

Such as nails ,bolts , hinges etc.

Such equipment as sold as stock by a store

called hardware store.


3/26

Purpose of using hardware

Provide better appearance

Makes the object functional Used as a connector

Types of hardware based on their uses Rough hardware- In building construction, hardware

meant to be concealed, such as bolts, nails, screws,spikes.

Finish hardware- such as hinges, locks, tower bolt,latches, etc., that has a finished appearance as well as afunction, esp. that used with doors, windows, andcabinets; may be considered part of the decorativetreatment of a room or building.

Finish hardware

Functional hardware makes object functional or

easy to use. For ex. Slider, hinges , metal plates.

Decorative hardware gives better appearance to

object. For ex. Matching hinges, handles , latches.

inish hardware can be divided into

functional and decorative hardware.

Tips to choose hardware products

It should be smooth appearance.

It can be able to bear weight of object.

There is no abnormal sound.

Material should be good.

It must be able to stand with corrosion, rustand damage.

Easy to use.

GL SS

Glass is Amorphous Brittle, Transparent /

Translucent, Good electrical insulator ,

Unaffected by air, water, acid or chemical

reagents definite crystal structure meansglass has high compressive strength Can

absorb, transmit and reflect light.

It has highly shining appearance and takesgood polishing.


14/26

Uses of glass

For glazing doors and windows.

Used for decoration.

Used for sound heat insulation.

Used for electric bulbs, cooking utensils andlaboratory equipments.

Used for partition walls.

Used for cabinets, show cases, shop fronts.Used for making furniture pieces.

Used as a fire retarder.

composition of glass

Lime - gives durability and hardness.

Soda - accelerates fusion of glass.

Potash - gives fire resisting property. Lead oxide - gives colour

Silica major constituent

Cullet

broken glass / glass chips

PL STICS

Plasticis the generic name for a family of synthetic

materials derived from petrochemicals. It is often productof two or more components.

There are many families of plastics and polymers beingused in construction industry. Examples of plastics usedin building are:

Acrylic

Composites

Expanded Polystyrene

Polycarbonate

Polyethylene Polypropylene

Polyvinyl Chloride

PROP RT S

Plastics have properties that make ideal building materials. Some of theseproperties are:

Plastics are strong yet lightweight, and so they are easy to transport &man oeuvre.

They are durable, knock-and scratch resistant with excellent weatherability.

They do not rot or corrode.

Plastics are easy to install; many have a snap-fit kind of jointingprocedures.

Plastics offer limitless possibilities in design achieved by extrusion,bending, moulding etc.

They can be given any range of colours by adding pigments.

The plastics are low conductors of heat and thus are used as insulationmaterials in green building concepts.

The plastics products can achieve tight seals.

They can be sawn and nailed employing standard carpentry tools andskills.

They can be easily removed and recycled.

They are bad conductors of electricity.


23/26

THE ADVANTAGES OF PLASTICS

1. Excellent electrical insulation properties.

2. Good insulation properties.

3. Certain plastics has good chemical

resistance.

4. Good resistance to shock and vibration.

5. Transparent and translucent.

6. Easily coloured.7. Easily assembled or jointed.

8. Repairing the self lubricating.

9. Good wear and scratch resistance.


24/26

THE DISADVANTAGES OF PLASTICS

Plastics may be degraded under the action ofdirect sunlight which reduces their mechanicalstrength.

Many plastics are flammable unless treated.

High embodied energy content Low modulus of elasticity: makes them

unsuitable for load-bearing applications.

Thermoplastics are subject to creep and soften

at moderate temperatures. Thermal expansion for most plastics is high:

adequate thermal movement has to be allowedin detailing.

Some of examples are Products of Plastics in Construction industryare as below

Pipes : Electrical Conduits, Rain Water & Sewage pipes,Plumbing, Gas Distributions.

Cabels : PVC Insulation on cables, Insulation Tapes .

Floorings : Flooring tiles & Rolls . Domes / sky lights : Opaque as well as transparent.

Roofing : Coloured or Double skinned for insulation.

Windows & doors : Extruded sections for Door and windows andpanels.

Storage tanks : Storage tanks. Hardware accessories : Washers, Nut bolts, Sleeves, Anchoring

wires.

Temporary structures: Guard cabins, tents

Insulation materials: PVC sheets, insulating membranes.
