At Tier 1 the gate is see-through. Bullets and other hitscan projectiles (30mm, 40mm, etc...) can pass through it, only the fence posts at both ends can block them.
Tier 2 Gate technology must be fully researched in the Weapons and Structures Tech Tree in order to be constructed.

Keep in mind that gates do not shoot at the enemy and so have limited defensive value on their own. In most cases, your gate should have active defenses, like Rifle Pillboxes, in front of it.
Trivia
Prior to Update 1.52, Gates would stay open/closed until the faction who constructed it interacted with it again. Due to this, this required additional awareness, as opened gates could let enemy players/vehicles through to an area.
This was later changed so that it would close automatically, in a larger anti-griefing response, where increased alt behavior led to the destruction of numerous equipment from both factions.
