The utility model relates to a frame rod of a building or a greenhouse, which comprises a plurality of frame rods each having a top plane forming a curved arc on both sides downwards, a curved arc and a downward inclined symmetry inner oblique, and each of which is connected with a reinforcing flange, and a concave arc is arranged at the center of the top plane. a curved surface； the main frame bar is partially or entirely embossed to form a groove having staggered irregularities, and the groove of the concave and convex groove is embossed with staggered obliquely spaced embossed points, whereby the frame bar has a thickness of 0.4 mm and has a conventional frame rod The 0.53mm plate has the same rigidity and strength and saves 25% in material cost. The creation board is thin and light, the board is thin and the cost is greatly reduced, and the farmers can purchase the greenhouse at a lower price for planting. The greenhouse constructed with a trapezoidal frame with two strengthened hem panels is also stronger than the conventional greenhouse. Not easy to brag.一種建築或溫室框架桿，包括複數框架桿均設一頂平面兩側往下形成彎弧，彎弧再往下接斜面對稱內斜，再各接一個強化折邊，頂平面中央得設凹弧曲面；主要框架桿以局部或全部壓花形成交錯凹凸的溝槽，凹凸的溝槽內壓設交錯斜排的間隔凹凸點壓紋，據此，框架桿板厚0.4mm即具有習知框架桿0.53mm板厚相同的剛性與強度，且節省了25%的材料成本。而本創作板薄且重量輕，板薄而成本大幅度降低，農民得以更低的價格購入溫室進行種植，本創作類似梯形並具兩強化折邊的框架桿建構之溫室亦較習知溫室堅固不易吹垮者。
