As to how I got the door off its hinges. The trap door like any door has hinges that are held together with pins. I remove the pins and presto I have a heavy ass door. I would be impossible for the the door to have pins that are welded at both ends, otherwise you couldn't get the thing off uneless you had a portable forge.

Objects with hardness or golem. Stuff you need adamantine to bypass

Yeah, I would have made the same call as your GM, but for different reasons. A piece of armor just has too much of its weight spread over too much area to make an effective bludgeoning weapon against a trap door. Perhaps if it is medium or heavy armor, and thus comes with gauntlets, I would allow you to try by punching with gauntlets (if armor comes with gauntlets, which medium and heavy armor does, you are always armed, as gauntlets are simple weapons), but I would not blame your GM for disallowing this either. Punching a metal door is generally not going to do anything but hurt your hand, no matter what you are wearing on it.

I think you misunderstood me, I want to use the trap door as a weapon.

This falls under the subject of what types of weapons are effective to damage which types of items. From the Core Rule Book:

Smashing Objects wrote:

Ineffective Weapons: Certain weapons just can't effectively deal damage to certain objects. For example, a bludgeoning weapon cannot be used to damage a rope. Likewise, most melee weapons have little effect on stone walls and doors, unless they are designed for breaking up stone, such as a pick or hammer.

Keep in mind, this gives only a couple examples, anything beyond that is entirely a GM judgement call.

Additionally, it is certainly not unreasonable for a GM to rule that a large piece of armor is generally ineffective as a weapon, because it is beyond unwieldy.

Additionally, say you are trying to break down a door. A conventional bludgeoning weapon is able to do such a thing, because it has all of its weight concentrated in a very small area, giving a very high pounds-per-square-inch ratio. An Adamantine Breastplate has its weight spread over a very large area, producing a very low pounds-per-square-inch ratio.

In this particular case the adamantine object in question a solid adamantine trap door.

I have a problem with a GM. He says since a piece of armor made of Adamantine provides DR than it wouldn't bypass hardness if used as an improvised weapon. Question is will it bypass hardness still?
