Cast steel nodes

Weight: 5~75T

Application: long span pipe truss steel structure

Customizable or nor: Yes

Product introduction 

Cast steel nodes now are widely used at some long span pipe truss steel structure, especially used at complicated intersection nodes due to its excellent machine and multiple architectural image .Nowadays cast steel nodes are found in railway station, highway station, airport, stadium and huge buildings.  

Our main material for the upright column is similar to followings:

Advantage

Shanghai Special Metal Co., Ltd adopts unique heat treatment to optimize the node structure, to enhance hardness, wear resistance and impact force.

The phase junction of steel pipe produced by Shanghai Special Metal Co., Ltd is directly cast molding, which makes steel structure bear force more rationally with stable structure. It avoids negative influence caused by the stress from a large number of welding.

Quality assurance

The fabrication route is governed by the provisions of the implemented Quality System ISO 9001: 2000. The standard documentation ensures the full traceability of every process step:

• Manufacturer test certificates according to DIN EN 10.204 § 3.1 including chemical composition, mechanical properties and non-destructive examination;

• Dimensional check supported with a “as-built“ sketch;

• Record of the heat treatment chart;
