As other answers pointed out, you don't necessarily need to learn anything about drums. Software packs provide you enough beats to play along.
However, if you don't have such software, or you don't feel like buying such software, here are a few beats that are very common in this genre. Write them down on Guitar Pro, or any other software able to generate MIDI drums, and you're good to go.
Some notes:
- Every symbol should be taken as a 16th note;
- All beats are in a 4/4 time signature;
o
marks a regular note, x
marks an accent (crash cymbal, for instance);
- The first line goes for cymbals (hi-hat, or ride), the middle line goes to the snare drum, and the bottom line to the bass/kick drum.

This four bar repeating beat is very common. Usually, there's some fill or slight difference in the last bar. This beat is common mostly due to being very flexible.
You may use it:
- At slower tempos (120~150 bpm, probably with 8th notes on the cymbals, instead of quarter notes) to play along heavy, slow rhythms.
- At faster tempos (150+ bpm) to play along fast-paced, powerful, rhythms. Example: Remembered by Firewind, the beat just after the introduction.
- For very fast-paced songs, you may add snare drums on every quarter note. Example: Electric Messiah, by Symphony X, the first beat you hear.
- For very fast tempos, but slow/heavy rhythms, the snares hit only on the 3rd quarter note, instead of every 2nd and 4th.
The rock-inspired single bass drum

This beat is lighter, and works well on most tempos. Fear of the Dark, by Iron Maiden, or Head Up High, by Firewind, use similar beats. Fear of the Dark moves around some kick drums, while Head Up High uses 8th notes on the cymbals, instead of quarters.
The gallop feel

o-oo--ooo-oo--oo|o-oo--ooo-oo--oo|o-oo--ooo-oo--oo|o-oo--ooo-oo--oo|
This is also a common beat. It usually goes along similar gallops on the guitars. Example: More Than Meets the Eye, by Testament, just after the intro.
The double tempo

I called it double tempo because the snare hits in every upbeat, while the bass drum kicks in every beat, which feels like the tempo is doubled. This is usually seen either in heavier styles, or folk styles. Fits well in fast-paced tempos. Example: Beer Beer, by Korpiklaani.
