Stainless Steel Reinforcement

The Ancon range of stainless steel reinforcingbar is the most comprehensive range available.Several grades including high proof strengthmaterial are available from stock.

Plain BarStaibar 304/Staibar 316 - An austeniticstainless steel reinforcing bar with a 0.2%proof stress of 200MPa and an ultimate tensilestress of 220MPa. It can be used for structuralengineering purposes.

Staifix Hiproof - A duplex stainless steelreinforcing bar with a 0.2% proof stress of200MPa and an ultimate tensile stress of500MPa. It is particularly suited for highlycorrosive environments such as in marinelocations. It is best used in applications wherehigh strength and corrosion resistance arerequired.

Staifix Hiproof - A duplex stainless steelreinforcing bar with a 0.2% proof stress of600-650MPa and an ultimate tensile stress of650-715MPa dependent upon diameter. It isbest used in applications requiring acombination of high strength and corrosionresistance or where maintenance or inspectionis impractical.

All bar grades are hot rolled and cold or warmworked to provide the stated mechanicalproperties. Chemical composition is given inthe table below.

Bending and ThreadingBars are available supplied cut to length, bentto schedule, threaded and engineered asspecified, please contact the Ancon TechnicalDepartment for maximum bar lengths.

Tying WireTying wire 1.2mm in diameter is available ingrade 316 stainless steel.

Ribbed BarStairib 304 - An austenitic stainless steelreinforcing bar with a minimum 0.2% proofstress of 500MPa and an ultimate tensilestress of 550MPa. It can be used for bothconcrete reinforcement and structuralengineering purposes.

Stairib 304 conforms to BS 6744:1986,Austenitic stainless steel bars for thereinforcement of concrete, for Grade 500reinforcement.

Stairib 316 - An austenitic stainless steelreinforcing bar with a minimum 0.2% proofstress of 500MPa and an ultimate tensile stressof 550MPa. It can be used for both concretereinforcement and structural engineeringpurposes. Stairib 316 is more corrosionresistant than Stairib 304 and is therefore moresuitable for use in aggressive environmentssuch as marine or heavy industrial locations.

Stairib 316 conforms to BS 6744:1986,Austenitic stainless steel bars for thereinforcement of concrete, for Grade 500reinforcement.

Physical PropertiesExtended Temperature PerformanceStainless Steels are high temperature alloysand Staibar, Stairib and Staifix Hiproof haveexcellent mechanical performance at elevatedtemperature. Tests show that on tensile testingat room temperature, after exposure to aheating regime of 600C for 2 hours, the barsshow a negligible reduction in tensile stresswhilst that for conventional carbon steel showsa significant drop in value over the sametemperature cycle. Austenitic stainless steelsdo not undergo the ductile to brittle conditionchange of conventional carbon steel astemperature falls.

Impact tests on notched bars show aductile mode of failure at temperatures aslow as -196C.

Austenitic stainless steel bars are thereforesuitable for use in cryogenic and hightemperature applications.

Low Magnetic PermeabilityAustenitic grades of stainless steel haveextremely low magnetic permeabilitycharacteristics and are virtually non-magnetic.

This property can be very helpful to thedesigner of structures housing equipment suchas electric arc furnaces, magnetic resonanceimaging (MRI) units or other sensitive electronicequipment where a neutral magneticenvironment is a requirement.Please note, Staifix Hiproof (Duplex) is amagnetic steel.

BT Stainless Steel CouplersThe BT system is one of the smallest and themost cost-effective coupler systems in ourrange, when used on large scale, high couplervolume projects. Stainless steel BT couplersare available in 12, 16, 20, 25, 28, 32, 36, 40,and 50mm bar diameters.

The end of each bar to be joined is cut squareand enlarged by cold forging. This increasesthe core diameter of the bar to ensure that thejoint is stronger than the bar.

Parallel metric threads are cut onto theenlarged ends. The threaded end can be prooftested to a force equal to the characteristicyield strength of the bar. A nominal allowanceof +50mm per threaded bar end should bemade for cutting square and cold forging.

The threaded ends of the bars are protected byan external plastic sheath. Couplers, which areusually supplied attached to the bar, have theirinternal threads protected by an internal plasticend cap. For certain applications, especiallywhere the BT system is being used in deeppours, the coupler end caps may not preventthe ingress of concrete fines. For theseapplications, further protection may berequired.

Other Ancon ProductsReinforcement Continuity SystemsReinforcement Continuity Systems are anincreasingly popular means of maintainingcontinuity of reinforcement at construction jointsin concrete. The Ancon Keybox systemeliminates the need to drill shuttering and cansimplify formwork design, thereby acceleratingthe construction process. It is available in bothstandard units and special configurations.Ancon KSN Anchors eliminate the need for o n-site bar straightening and are available asstandard in 12mm, 16mm and 20mmdiameters. The system is also available with a re-useable rebate former.

Shear Load ConnectorsAncon DSD and ESD Shear Load Connectorsare used to transfer shear across expansionand contraction joints in concrete. They aremore effective at transferring load and allowingmovement to take place than standard dowels,and can be used to eliminate double columnsat structural movement joints in buildings. ALockable dowel is also available for temporarymovement joints in post-tensioned concreteframes.

Punching Shear ReinforcementAncon Shearfix is used within a slab to provideadditional reinforcement from punching sheararound columns. The system consists ofdouble-headed steel studs welded to flat railsand is designed to suit the load conditions andslab depth at each column using freecalculation software from Ancon.

Masonry Support SystemsMasonry cladding on concrete or steel framesis normally supported from stainless steelsupport systems. Ancon MDC Systems createa continuous angle to support the outer leaf ofmasonry. Ancon Individual Brackets supportmasonry features such as curves and arches.

Special FabricationsAncon is an ASSDA accredited specialistfabricator and has a wealth of experience inworking with a variety of material grades. Highintegrity steel components are supplied to awide range of industries including CivilEngineering, Building, Infrastructure, WaterTreatment, Nuclear and Mining.
