A strength pure generally has 1 attack and 60-99 strength. This is because at 60 strength, you can wear the obsidian maul. This is a very strong weapon, and you can already hit around 15-20 on combat 35. (Combat 35 is when most people get 60 strength). They're quite effective actually. You'll be 99 strength at around combat level 50-55, depending on your HP level. I'm sure there's a way to calculate this. Ofcourse, if you don't want the hp levels, you can always do barbarian fishing all the way to 99, but this takes a very long time and is nearly impossible.
For pking with a strength pure, I'd suggest just using the maul. Simple as that. You'll be hitting quite well, and a few good consecutive hits will knock your opponent down.
A range tank is a .. Ranger, with 45+ defence. I don't know alot about this, so I'll go to gmaul rusher.
A gmaul rusher usually has 50 attack and 50-99 strength. This is because 50 attack and 50 strength are needed to wield them.
This is often combined with 58, 72, 82 or 94 magic. You basically just cast ice rush, ice .. thingy (Dunno what the 72 one is called), ice blitz or ice barrage once or twice, then run towards them and use your gmaul specs. This will work exceptionally well against unarmored foes, but when you're a high combat, expect your targets to wield rune or even dragon items; your 50 attack will not always hit through that.
Finally, a zerker pure. My favourite. I have one of those myself on 07, actually.
A zerker pure is a pure with 45 defence, 60/70 or 99 attack, and 99 strength. (Strength level may vary, but generally attack is NEVER higher than your strength level)
Often this is combined with 94 magic for ice barrage and a high ranged level. This is because zerkers are ideal for hybridding.
With the ideal zerker (99 magic, 99 strength, 60 attack, 99 ranged, 99hp, 45 def, 52 prayer) you will be combat 94.
Hope this helped. If you need any other information that I forgot, feel free to post. I like to help.
