Macalloy 1030 Macalloy S1030 Post Tensioning System

The Macalloy 1030 Post-tensioning bar consists of high tensile alloy steel bars in diameters from 25mm to 75mm provided with cold rolled threads for part or full length, together with a range of fittings. Bars from 25mm to 50mm diameter obtain their specified properties by cold working. Bars of 75mm diameter obtain their specified PT Bar Prestressing - FreyssibarDeveloped by Freyssinet, this prestressing system comprises of a wide range of fully threaded bar and complimentary anchoring, coupling and extension devices. Freyssibar is used for post tensioning, prestressed ground anchors and any application involving temporary or permanent tie-rods, lifting, suspension, prestressed splices etc. Pre-stressed Cable Anchors Grouted Ground AnchorsThe Anchors transfer tensile load to the ground to take of stresses generated due to loss of effective stress. In Geo-technical engineering it is termed as Prestressed Post tensioned Grouted Ground Anchors. The ground anchors can be made by using Wire or cable Anchors of high grade steel Bars.

Prestressed Concrete - Method, Advantages & Disadvantages

Nov 25, 2019 · Engineers come with the solution to introducing High strength steel bars into concrete members. Using this method they have overcome the problem of tensile stress which has allowed the engineer to achieve various possibilities such as reducing Steel Construction - AEFACThreaded bar is becoming popular in the structural engineering industry. It is used as replacement for long bolts as well as concrete anchors. It is also known as thread bar, threaded rod, Sampson rod or All-thread. This product is not covered under Australian Standard AS 1252, High strength steel SupFRP® GFRP Hollow Injection Bolt -SupFRP produces high The SupFRP® GFRP Hollow Bolt is developed with high tensile load and pressure resistance. It combines rock bolt with injection function. The GFRP Hollow Bolt can be widely applied in geotechnical engineering projects. After injection work, the bolt can remain in the borehole and bear load with plate and nut at the end.

General speaking, the injection hollow bar anchor is in the diameter of 25mm to 38mm. the length is 3.0m to 4.0m. The hollow rock bolts are mainly installed into the crown section of the tunnel. Drilling rigs and grouting platforms provide power and support. THE FREYSSINET PRESTRESSED CONCRETE CO.

What Is Reinforced Cement Concrete? Origin & Advantages

Cold worked Steel Bar The cold worked steel bars are manufactured at the temperature range of 20°C to 36°C, which is obtained from the hot rolled steel bar. The cold worked steel bars contain less ductility compared to the hot rolled steel bar. So those bars are used for small-scale structures. Mild Steel The tensile strength of mild steel is in the range of 275 N/Sqmm to 300 N/Sqmm. There are no deformation ribs on the mild steel Zinc Plated High Tensile Steel Studding Bolts M16 x 3 Metre High Tensile Grade 8.8 Studding (Threaded Rod), Steel Bright Zinc Plated DIN 975 1941270 M18 x 1 Metre High Tensile Grade 8.8 Studding (Threaded Rod), Self Colour DIN 975 1941273 M18 x 3 Metre High Tensile Grade 8.8 Studding (Threaded TECHNICAL BAR SYSTEM - Rock BoltFULLY THREADED BAR * High grade steel effectively reduces the diameter of the bar allowing for easier handling and a smaller bore hole. * Continuous thread makes connections, possible at any point and increases bonding. * Coarse thread and surface hardening allow for rough handling. * Pre-stressing possible for active anchors
