SAS bar system which features high quality thread bars of various grades, up to prestressing steel quality, in a range of diameter from 12 to 75mm. We provide various system solutions for variety of technical engineering purposes, including thread bar anchors for mining and tunneling, reinforcement connections, form ties, tie rods, soil nails, micropiles, rock and soil anchors for geotechnical applications as well as prestressing tendons for post-tensioning.
SAS system products have made us the leading global supplier of hot-rolled thread bars. We have a warehouse in SIngapore and hence can meet the needs of our clients wherever possible.
Features and Benefits of the SAS thread bar:
- Continuous hot rolled thread along full bar length
- Can be cut and coupled anywhere along its length
- Bond of Tw = 4.3 N/mm2 to the cement grout
- State of the art corrosion protection systems
- High quality conformance to ISO 9001 and TS 16949
This is how our steel is made.
The centrepiece of our production is a 22-stand continuous small-section rolling mill in which materials of diverse grades, pre-heated up to approximately 1,100 °C in the walking beam furnace, are rolled out to diameters between 12 mm and 75 mm. Part of the material is already tempered in the rolling mill utilizing the rolling heat. After cooling and cutting, the material goes to one of our 9 finishing lines for further processing.
In the steel bar finishing lines, our SAH steel bars with diameters ranging from 12 to 40 mm are annealed, straightened, sawed, shot-blasted, chamfered and checked for surface defects. Part of the bar material is further refined by using peeling and straightening/polishing, followed by another surface check and/or ultrasonic testing. Additional production stages comprise sawing including end forming, turning, grinding, deburring and gear cutting.
Our SAS thread bars with screwable continuous coarse threads ranging from 12 mm to 75 mm in diameter are either delivered pre-assembled or undergo additional treatment processes, such as stretching followed by annealing in order to produce special grades with specific strength values. The screwability of the thread bars is checked continuously.
Part of the material is subjected to further in-house processing such as bending, locking and other assembly steps, which enable us to offer our customers complete system solutions.
The required accessories are also produced in-house using various gang drilling machines, whirling machines and CNC lathes.
SAS reinforcing systems
for reinforced concrete and road construction.
SAS reinforcing systems are widely used throughout the world in structural engineering as well as building and road construction.
The systems consist of hot-rolled SAS thread bars and accessories and are available in the grades SAS 500/550, SAS 550/620 and SAS 555/700. The optimally suited and versatile accessories are used to couple bars and minimize anchorage lengths by means of special reinforcement end anchorages that can also be installed in difficult application conditions.
The thread bars of our SAS reinforcing systems have been tried and proven for decades and now play an indispensable role in modern reinforced concrete construction.
They have been successfully installed in numerous reinforced concrete structures, e.g. in the ADAC building in Munich (FRG), Berlin Government Building (FRG), ballastless track (track supporting slabs) of the Nürnberg & Erfurt ICE high speed tracks (FRG) and in the Rheinfelden hydroelectric power station (FRG).
SAS 670/800 high-strength reinforcement is an innovate product far surpassing conventional reinforcement and is primarily used in the construction of high-rise buildings.
High-strength reinforcement systems feature an increased yield and ultimate strength. The increased yield strength enables the construction of slender yet stable structural elements thus helping save resources and costs – convincing advantages for our customers who have since successfully installed our SAS 670/800 high-strength reinforcement in numerous building projects such as the Frankfurt Opera Tower (FRG), Dancing Towers in Hamburg (FRG) and World Trade Center in New York (USA). Many other buildings are currently under design or construction.
SAS thread bar systems for soil and foundation engineering and harbour construction.
SAS thread bar systems have been successfully used for decades as micropiles, soil nails, rock and soil anchors, and tension ties in special geotechnical works and harbour construction.
The broad product range includes various systems featuring a variety of steel grades such as SAS 500/550, SAS 550/620, SAS 555/700, SAS 670/800, SAS 950/1050 and SAS 838/1035 as well as different types of corrosion protection systems: Galvanized, standard corrosion protection by means of a cement grout envelope, or durable double corrosion protection.
Our SAS systems can thus be used for a wide range of applications and be flexibly tailored to satisfy individual customer requirements and environmental conditions.
Numerous national and European approvals are proof of the reliability and efficiency of our thread bar systems in geotechnical engineering.
Our customers have already successfully installed our SAS micropiles, soil nails, rock and soil anchors, and tension ties in various projects worldwide, e.g. the new Gateway Bridge in Brisbane, Australia, Dubai Dry Dock, Al Salam Street in Abu Dhabi and Koge Harbour in Denmark.
SAS anchor systems for mining and tunnelling application.
SAS anchor systems such as the SAS expansion shell anchor or SAS resin anchor systems are either individually assembled or supplied as preassembled anchor systems. SAS anchor systems effectively improve the stability of underground rock masses. The increased load-bearing capacity of the rock conditions enables an early construction start, thus providing both technical and economic advantages.
Thanks to our systems flexible application options, our customers can choose next to mechanical and chemical anchors and bolts from a variety of anchoring systems, e.g. eyebolt anchors, hook anchors and additional roof support structures, which are all custom-tailored to satisfy individual project requirements
