Joining the Iron are defender Ricky Gabriel, striker Nigel Neita and midfielder Connor Bolton from Quinton's previous club Enfield Town.
Twenty-six-year old Gabriel (pictured) was part of Quinton's side that lost the Ryman League play-off semi-final at Dulwich Hamlet last May, making a total of forty-three appearances and scored 7 goals for the North London club.
He joined Enfield from local Spartan South Midlands League side Brimsdown Rovers in early 2015 and had a spell at Dover Athletic after playing in the USL Pro League for Antigua Barracuda FC.
Neita started his career at Arsenal and signed a professional contract in 2011.
During his two years with the Gunners he was called up for Jamaica's friendly against Costa Rica in March 2012.
After leaving Arsenal, he moved on to Dulwich Hamlet in 2013 and then Metropolitan Police a year later.
Now 23, he was also at Enfield Town with Quinton last season and made eighteen appearances, scoring twice.
Bolton is 22 and at home on the left side of midfield.
Another with Quinton at Enfield last season, Bolton also spent time on loan at SSML side Hadley and Ryman North outfit Ware last season.
He was part of the Enfield under-21 side that won the Middlesex Premier Cup in 2015.
