# 按树种的木材重量：对照表、含水率与卡车载重

一车生橡木和一车干云杉是两辆不同的卡车。树种密度、含水率与载重限制——它们如何叠加。

## 为什么不只看体积

卡车、叉车、屋面结构和挂车都认公斤，不认板尺。订 2 m³ 橡木而不是 2 m³ 松木，会让整车重量翻倍——让原本合法的载重超过轴荷。

## 典型密度（气干）

西部红柏约 380 kg/m³，云杉和冷杉约 450，白松约 500，花旗松约 530，南方黄松约 550–600，樱桃木约 600，黑胡桃约 650，白蜡木与桦木约 670–700，橡木约 750，榉木与硬枫约 750。这些是气干近似值——单块板材会有差异。

## 含水率改变一切

生材所含的水重几乎可以达到窑干材的两倍：生橡木接近 1000 kg/m³，而窑干橡木约 750。结构材一般干燥到 18–20%，家具用材 8–12%。要称重？同时问一句含水率。

## 载重校核

一辆典型的一吨皮卡合法载重约 1000–1200 kg。这大致是 1.5 m³ 窑干橡木——或 2.2 m³ 云杉。别靠目测装车：把体积乘以树种密度，再和额定载重比较；[木材重量计算器](https://nestingcalc.com/cn/lumber-weight-calculator/) 会替你做这件事，并包含你所选的密度。

## 从树种到卡车

[木材重量计算器](https://nestingcalc.com/cn/lumber-weight-calculator/) 用树种密度或自定义值把板材清单换算成重量，合计整车，并与你的卡车载重比对，方便你正确分批运输。
