Mechanical Engineering tenders published on TenderBulletins.co.za are gathered here, covering RFQs, RFPs, EOIs and official Tender Bulletin notices for organisations seeking mechanical engineering suppliers and contractors.

Tenders in this category ask suppliers to quote on mechanical engineering - anything from once-off supply contracts to multi-year service agreements, depending on the issuing organisation's needs. Requirements, BEE and compliance criteria differ per tender, so review each listing individually.

Based on the tenders we have tracked, you will regularly see tenders here from Department of Public Works, Transnet SOC Ltd and City of Cape Town; and activity is concentrated in Gauteng, KwaZulu-Natal and Western Cape.

Every entry links through to the original tender notice, including the closing date, tender number and any attached specification documents, so you can check eligibility and submission requirements before you apply.

Click through to any listing below for the full tender details, closing date and downloadable documentation, then contact the relevant person to submit your bid. If you need mechanical engineering suppliers yourself, use our Send Us Your Tenders page to reach our subscriber network directly and receive quotations from suitable suppliers and service providers.
