The Steelmen moved to the top of the table with their home win, but last season’s runners-up Llandovery, RGC 1404, Newport, Pontypridd and Cross Keys will be looking to overtake them with a second successive e bonus point win.
Llandovery host Cardiff, while RGC head south to face Swansea. Pontypridd entertain Llanelli, while Cross Keys take on a tricky trip to Carmarthen Quins.
Reigning champions Merthyr kick-off their campaign at The Wern with a game against Bedwas, who beat them there 37-24 last season.
