地板是工程硬木地板，合同隻說了hardwood 樓梯和一樓地板，我基本要求是一樣的材料，沒想整出兩種hardwood，是不是oa

原文如下：

I hope that I am understanding your question correctly.  The floors are an engineered hardwood that is installed in planks.  The stairs are solid oak treads that are stained to compliment the floors.  This makes for a quality installation that will last for years to come.
