More Info
SNU is a special product of sahand industrial group that is designed to use for micropile,nailing and anchor bolts.Nut is available for sizes from 16 to 50 mm of rebars and all of threads are exactly same as SST coupler threads.Lenght of thread is available up to 300 mm according to the customer order. SNU strength is same as sst coupler and reaching to FSU of rebar in guaranteed by sahand industrial group.

This coupler replaces conventional hooked reinforcing bar also simplifies reinforcing bar placement and lowers placing costs . Head area of this coupler exceeds 5 times bar area (net force bearing area is 4x) according to the cone shape shearing theory so using of this coupler reduces the Ldt (embedment length of the rebar) couplers meet requirements of ACI318-08 section 12.6.

short length of rebars when rebars’ length is less than 20cm.There are some bolts that hold the rebar firmly inside the coupler and the opposite side of coupler is threaded same as SST coupler that rebar is fastened inside it.SAHAND produces couplers from 16 mm to 50 mm and other sizes according to customers’ need is available.The solid round steel DIN 1.1191 is used for producing the couplers. Universal and CNC machines are used to produce the couplers.The QC department controls the quality in each step of production line.The couplers pass the international codes and standards such as,ACI318 ACI349,ACI352,BS8110 and DIN1045.

Due to facing problems in process of rebar welding directly to the steel structures and not any guarantee of quality in welded area,SAHAND
industrial group has designed and produce special coupler that is weldable to the steel structure. This coupler is use to connect rebars to the steel structure No pre-heating needed before welding the coupler.Welding must be done according to the manual inside coupler package.The solid steel bar is used for producing is DIN 1.1141 and 1.1151 and CNC machines are used to produce the couplers.The QC department controls the quality of couplers in each step of production line ,the couplers pass the international codes and standards,ACI318,ACI349, BS8110and DIN1045.

This coupler is produced in two types.firs type must be welded to the rebars (SWR) on one side and the second side is threaded , so the threaded rebar will be fasten on this side.the second type of coupler must be welded to the rebar on both side of coupler (SWW).Swr and sww couplers are welded directly to the rebars and bear specified ultimate strength of rebar same as other SAHAND couplers.This coupler is used in application in which rebars are shorter than the length is needed for lap splices also can be used instead of stl coupler comparing to the stl coupler the price is very cheaper.SAHAND suggestion is using this coupler for rebars bigger than 25mm.For getting best result, welding process of this coupler must be according to sahand welding instructions.It is a must to use professional and certified person to weld the couplers.

The standard or right threaded coupler is proposed as the most widely used in every part of the concrete structure. This type of coupler is used in place that at least one of rebars is able to be rotated. Internal thread of the coupler is right hand and complete part of thread on the rebar shall .be fastened inside the coupler. SAHAND produces this type of coupler from 16 mm up to 50 mm and any other request of customers is possible For the production of coupler solid steel bar (DIN 1.1191) is used as raw material.Universal and CNC machine tools is used in production line.e At each stage of production ,QC department controls coupler specified dimensions and after confirmation of complete manufacturing process in the first step the couplers are transferred to the next step. The couplers quality meets the Iran national building regulations and international codes and standards such as ACI 318, DIN1045 and BS 8110.0
