Reinforced Frame is a technology that can be researched at the Hvy Weapons Factory in Tech Level 4. It costs 450 Carbon and 250 Nova, and gives Hvy Weapons Factory units +10% Hit Points. It is available to the Gungans, Trade Federation, and Wookiees. Strengthened Frame must be researched before it becomes available.

This technology is more expensive than Strengthened Frame, while giving the same bonus. If the player can afford it, it's a decent upgrade that will keep the player's Heavy Weapons alive longer.

"At Tech Level 4, the Reinforced Frame technology gives Heavy Weapons even more hit points."
