2. Structural Designs

SME has attained significant experience in structural solutions throughout recent years.  The two main specifications to which all structures comply are:

  • Design of Steel Structures: AA 114001 Issue 11

This specification defines the different loading conditions / combinations taking an Ultimate and Serviceability load factor into account. 

  • Design of members, connections and welding: SANS 10162 

This specification is in general used for the design of welded joints and bolt connections. 

With the help of Structural Analysis Software such as Prokon Structures and various Autodesk tools as mentioned under General Mechanical Designs we ensure cost effective solutions are provided to our customers.


An important aspect in structural designs is that all designs are signed-off by a registered professional engineer.

5. Electrical Design

SME’s electrical department offer turnkey projects in the electrical, electronics and control environment. This ranges from Distribution Boards (DB) and PLC Panels to Variable Fan Speed controllers and our latest Multi-Application Controllers (MAC).

Our main focus is to design and manufacture control systems for all mechanical products fitted with electrical equipment. Only reputable components are used and all workmanship is of the highest quality. Subject to this, Factory Acceptance and Testing (FAT) forms an integral part of our success. All products are subjected to various simulated harsh environments in our climate control chamber before being ruled as fit for purpose. Subsequent to this shock, vibration & EMI/EMC qualification tests are performed to ensure our products are fit for the harsh environments in which it operates. 

Our field of expertise:

  • Control Systems: Design & Develop specific to a custom requirement; Multi-Application Controller (such as: Stand-alone variable fan speed controller); Programmable Logic Controllers (PLC); CANBUS& RS485 communication; Wireless LAN & Blue tooth communication interfaces with a GSM ability to monitor and provide input from any location. 
  • Design, Manufacturing and Population of Distribution Boards (DB), PLC Panels, Control panels, Customized Man Machine Interfaces (MMI), Alternators & Gensets (Auxiliary Power Units).
  • Installation of Low to Medium Voltage power cabling, Instrumentation cabling, Communication cabling; Sensor equipment such NTC & Thermocouple Probes and Pressure transducers; Instrumentation and controllers.
