BUILDING MATERIALS

AND CONSTRUCTION

IV

STEEL . . .

• STEEL is a common building material used throughout the construction industry.

• Its primary purpose is to form a skeleton for the building or structure essentially the part of the structure that holds everything up and together.

• Steel has many advantages when compared to other structural building materials such as concrete , timber , plastics and newer composite materials.

STAINLESS STEEL . . • ALLOY OF IRON AND CARBON , CHROMIUM, NICKEL

& MAGNESIUM• Architects, designers, and building specialists

throughout the world will unanimously testify to the advantages of stainless steel in interior building contexts.

• Stainless steel is renowned above all for its resistance to corrosion and its attractive, striking appearance. Both are due to the presence of the chromium as an alloying element.

• Stainless steel also boasts physicals and mechanical properties that make it an exceptionally useful and desirable material for the widest variety of applications.

• MALLEABILITYCan be hammered and pressed into shape

• DUCTILITYCan be drawn into fine wire

• ELASTICITYRegains its shape after being deformed

PROPERTIES . . .

• HARDNESSResists being scratched or cut

• BRITTLENESSExtremely hard and therefore , will not break easily

• CONDUCTIVITYAbility to conduct heat or electricity

INTERIORS USING STEEL . . .

• CEILING

• WALLS

• INTERIORS OF KITCHEN

• FLOORING

FURNITURES

• STAIR CASES

• FIRE PLACE

Cost-effective and totally unexpected, the ribbed metal ceiling in this Coconut Grove, Florida home by Mateu Architecture echoes metallic elements used in the kitchen and outside the house.

RIBBED METAL CEILING

Stainless steel tiles aren’t unusual in bathrooms or as back splashes in modern kitchens, but it’s their use here to cover an entire living room wall that puts them in a whole new light.

Shimmering and textural, this tile application creates an eye-catching accent wall.

Stainless Steel Mosaic Wall Tiles

Shiny metal is much more than just an accent in this modular kitchen. Calling to mind commercial kitchens in which every surface must be easily sanitized, but on a smaller scale, the minimalist result is clutter-free and contrasts nicely with a natural wood floor.

Japanese Alluminum Modular Kitchen

Looking like it was carved from one solid block of metal, this curving sofa in a shape reminiscent of a sea shell is definitely a bold way to bring metals into your living room.

Ultramodern Steel Sofa

Seemingly seamless, the B3 Mono block by Bulthaup so strongly resembles a solid block of metal that it causes people to wonder whether you hauled it up to your apartment with a crane. Custom-made of high-grade stainless steel, these lustrous kitchen islands are totally lust-worthy.

Steel Stairs

Since stairs are often located in the heart of a home, they provide another opportunity to stun with steel. These three creative sets of metal stairs in unusual designs certainly stand out.

Aluminium WallsFor this prefabricated home in Kanazawa, Japan, architecture firm Atelier Tekuto formed the interior spaces using molded aluminum rings, left unfinished so that the wall and ceiling surfaces of the home are entirely metallic. The architects cut energy costs by 80% by putting the reflective qualities of aluminum to good use, installing small LED lights directly into the ceilings and walls.

Contemporary Steel Fireplace

A column of steel stretching from floor to ceiling makes the living room fireplace an even bigger draw. These three examples include minimalist matte cold-rolled steel, a more artistic reflective stainless steel surround and a  free-standing modern fireplace that even includes storage space.

Copper Water Wall

Water fountains are perhaps one of the easiest ways to bring metallics into your home in a big, bold way – in many cases, you simply hang the fountain on wall brackets and plug it in. Other installations can be more complex, like built-in water walls. The reflective qualities of the metal give the falling water even more sparkle.

AVAILABLE FINISHES FOR FERRITIC STAINLESS STEELS ARE THE SAME AS THOSE FOR AUSTENTIC GRADES. THE MOST COMMON INCLUDE

•COLD ROLLED FINISHES

•BRUSHED AND POLISHED FINISHES

•PATTERNED FINISHES

•SPECIAL DECORATIVE FINISHES

SURFACE FINISHES . .

COLD ROLLED FINISHES

•These standard finishes are the direct result of the stainless steel processing cycle at the mill.

•The most common are 2B and BA/2R. Both ara often used for interior building applications.

•2B finish has a smooth, fairly bright appearance, achieved by cold rolling, annealing and pickling, following by final skin pass rolling using perfectly smooth rolls.

•BA/2R finish is obtained by bright annealing in an inert gas atmosphere after cold rolling, following by a final skin pass. This highly attractive surface is smoother, brighter and more effecive than 2B

BRUSHED AND POLISHED FINISHES

•These finishes can be applied to both 2B and BA surfaces.

•The grade of abrasive used determines the fineness or coarseness of the finish.

•Mechanically applied, these finishes can be achieved with either wet or dry grinding and can be used for many inner building applications.

•They are highly suitable for wide areas of stainless steel cladding.

PATTERNED FINISHES

•Proprietary pattern-rolled finishes are also widely employed in buildings.

•These are usually achieved by rolling with patterned rolls.

•As with brushed surfaces, stainless steels with patterned surfaces are suitable for extensive, flat, indoor areas, such as paneling or claddings

•In areas of heavy public traffic, such as building entrances, lift cages and airport terminals, where surfaces are susceptible to knocks and scratches, patterned surfaces are less likely to show damage.

SPECIAL DECORATIVE FINISHES

•Modern techniques and processes make it possible to create exciting and dynamic graphic designs.

•Beside brushed, polished and patterned surfaces, acid etched, shot blasted or coloured surfaces are also available.

•These techniques provide an even wider range of surface variations.

•Indeed, for architects working on interior building applications, stainless steels provide a huge range of design possibilities.
