Bullet For My Valentine scored a double - including being named best British band - at the Kerrang! Awards.
The Welsh musicians picked up the gong for the third year running.
They were also named best live band, following a headline appearance at this year's Download Festival.
More than six million rock and metal fans voted for their favourites at Kerrang! Magazine's 17th annual awards ceremony, held in London last night.
Acting heart-throb turned singer Jared Leto's band 30 Seconds To Mars pipped Paramore to be named best international band. The group are touring in Australia.
But Paramore took the best album trophy for Brand New Eyes.
Kerrang! Magazine editor Nichola Browne said: "It's brilliant to see that our British rock and metal scene is so highly regarded and supported."
Scottish favourites Biffy Clyro, who are nominated for this year's Barclaycard Mercury Prize, won best video for the track The Captain, which sees the band captured on a boat out on the high seas.
Surrey's You Me At Six were voted best single winners for Liquid Confidence, while London-based metal band Rise to Remain were crowned best British newcomers.
Fronted by Bruce Dickinson's son Austin, the band are working on their debut album.
Best international newcomer went to Californians Trash Talk.
In addition to the eight public voted for categories, several special awards were presented on the night.
Motley Crue received the Kerrang! hall of fame trophy, following in the footsteps of legends including Black Sabbath, Bon Jovi, AC/DC, Judas Priest and Slayer.
Two posthumous awards were given out. The Kerrang! icon award went to Ronnie James Dio, who died in May.
Dio performed in Rainbow, Black Sabbath, and up until his death, Heaven & Hell and his award was accepted by his widow Wendy.
Slipknot bassist and songwriter Paul Gray, who also died in May, was honoured with the Kerrang! services to metal award.
Lostprophets were honoured with classic songwriter, while "punk poet" Frank Turner collected the no half measures award.
German band Rammstein were presented with the inspiration award.
