Company Overview

Shandong Le Ren Special Steel CO., Ltd. owns three factories to produce all kinds of steel rod, steel bar and finished steel products. Among three factories, one is to produce steel bars such as annealed, normalized and quenched and tempered steel bar and pipe, cold drawn, peeled, ground and polished steel bar etc; one is to produce threaded or knurled steel rod and steel bar; another one is to do steel bar, steel rods or steel pipe machining. 


In the tactories, we have complete and advanced production, inspection and testing facilities such as shot blasting machines, cold drawing machines,straightening machines, annealing furnace, quenching and tempering furnaces, threading machines, cnc machines, welding machines etc, and inspections and testing facilities to inspect dimension tolernaces, corner radius, length, straightness, surface roughness, mechanical properties, AKV, UT testing, Eddy testing and MPI testing etc. All of these, including more than twenty years production and exporting experiences, we can supply you good quality products and services.

Inspection

Our factory is equipped with complete inspection and testing facilities to inspect steel bar dimension tolernaces, corner radius, length, straightness, surface roughness, mechanical properties, AKV, UT testing, Eddy testing and MPI testing etc.


Packing & Delivery

Most of our steel bar are cold drawn, peeled, ground and polished steel bar which require good surface and straightness. So steel bar packing is very important to keep good quality. We use several kinds of steel bar packing according to your technical requirements.
