三角挡粮门主要由门框、门扇、放粮口、手轮锁紧装置、安全爬梯组成。该门主要用于存粮高度8米以下的高大平房仓。优点：设计合理，安全环保，外形美观，使用方便。
门框：选用GB9787热轧等边角钢，安装于仓门洞口内侧，与墙体内的预埋件焊接或用膨胀螺栓固定。
门扇：主要由底扇、顶扇及中扇组成，门扇骨架采用GB6728-2002冷弯矩形钢焊接而成，门扇面板采用GB/T708-88优质冷板，门扇内用50mm厚阻燃型聚苯乙烯泡沫板做保温隔热材料。安装时，各扇之间留有合理间隙，间隙用带钢或矩形钢管搭接，防止粮食外流。底扇与地面以及顶扇与仓内挡粮檐之间的间隙用“三元乙丙”胶条密封。
放粮口：在靠下的两组门扇上分别设计了2个或4个放粮口，需要出仓时，提起放粮口的插板即可。最下面两扇门可以拆卸，便于出粮清仓。
手轮锁紧装置：该设计，是在入粮前将挡粮门关闭锁紧，使挡粮门形成整体，有效增强挡粮门的抗压性和稳定性，保障挡粮门自身和工作人员的安全。
安全爬梯：在挡粮门一侧，设计安装了安全爬梯，它可以方便工作人员关闭或开启挡粮门，在特殊情况下，与安全绳配合，可以对工作人员起到保护作用
