概述

铁丝网围栏通常在比木材更宽的柱间距上运行,通常为 10 英尺,因为网片本身在柱之间承载的自身重量非常小。当选择铁丝网时,该计算器默认为该间距和标准样式,高度和其他所有内容仍然完全可编辑。

立柱、角和末端计数以及具体公式与此处任何其他材料的工作方式相同:它们是根据您的实际围栏长度和间距计算的,而不是每典型码的固定数字。

假设前提

  • Post spacing defaults to 10 feet, the common chain link spacing, and stays editable.
  • Concrete is computed for every post the same way it is for wood posts.
  • The calculator counts posts, rails/rails-equivalent and concrete, not fabric roll quantities, which the chain link fabric calculator handles separately.

常见错误

  • 假设铁丝网不需要混凝土,因为它很轻;终端和角柱仍然承受来自网片的真正张力,并且需要适当的基础。
  • 使用木栅栏柱间距(8英尺)代替更宽间距的铁丝网片,这会增加不必要的立柱和成本。
  • 规划结构时在硬件计数中忘记了顶部横梁或张力线。

围栏计算公式

和计算器相同的数学,用大白话写出来。没有黑箱。

  • 跨数

    sections = max(ceil(effective run / post spacing), 1)

  • 立柱数

    posts = (sections + 1) along the run, minus named corner and end posts already placed, plus 2 gate posts per gate

  • 有效长度

    effective run = total length - sum of gate widths

  • 横梁数

    total rails = sections x rails per section

  • 板条数

    pickets = ceil(run in inches / (picket width + gap)); total = ceil(raw x (1 + waste %))

  • 交错叠放式间距

    pitch = picket width - 1 inch overlap

  • 围栏板数

    full panels = floor(run / panel width); add 1 cut panel if the remainder is over 0.01 ft; total = ceil(raw x (1 + waste %))

  • 混凝土体积

    per-hole = pi x (diameter / 2)^2 x depth; total = per-hole x posts; bags = ceil(total / bag yield)

  • 坡度调整后长度

    slope run = effective run / cos(atan(slope % / 100)); shown alongside, counts use the flat run

  • 成本

    materials = (posts x post price + rails x rail price + infill x unit price + 60 lb bags x bag price) x regional multiplier; labor = effective run x labor per ft x terrain multiplier x regional multiplier; installed total = materials + gate hardware + removal + permit + labor

计算器显示的每个数字都由这些公式作用于你的输入得出。

The chain link fence calculator works out the full material list for a chain link run from three inputs: your total fence length, the height you want, and the post spacing, which defaults to 10 feet because chain link fabric is designed to span that distance without sagging the way a wood panel would at the same interval. From those numbers it derives line post count, terminal posts at every corner and end, the top rail length needed to tie the posts together, and the concrete volume for every hole, the same volume math used by the fence post concrete calculator. If you already know how many linear feet you are fencing but have not settled on spacing, the fence post calculator is a useful starting point for comparing spacing options side by side before locking in the chain link defaults here.

Posts and rail are only half of a chain link project; the fabric itself is sold separately in rolls, and matching roll count to your run length is a different calculation from post spacing. The chain link fabric calculator handles that half: how many rolls a given run needs, what cut piece is left over, and how many splices join the rolls together. Running both calculators against the same total length keeps the post list and the fabric list consistent with each other. Chain link is also the material most often compared on price against wood, since both are common budget choices for a basic perimeter; the wood vs chain link fence cost comparison walks through why chain link usually comes out cheaper per linear foot once labor is included, while the chain link cost per foot guide breaks that number down by height and gauge.

Post spacing is the single input with the biggest effect on the total post count and therefore most of the cost, since every added post also means another hole and another bag count. The 10 foot default used here reflects common residential practice, but it is not a code requirement, and tighter spacing, closer to 8 feet, is reasonable in high wind areas or where privacy slats will be added to the fabric later, since slats catch wind the open fabric does not. The how far apart should fence posts be guide covers that tradeoff for chain link and other materials together. Whatever spacing you choose, do not assume chain link posts can skip concrete because the fabric itself is light: corner, end and gate posts absorb real tension once the fabric is stretched and laced, and an under-set terminal post will lean within a season or two. For the full sequence of laying out, setting and stretching a chain link run, see the chain link fence installation guide.

Once the post, rail and fabric quantities are settled, the fence cost calculator turns them into a dollar total using your own local unit prices for posts, rail, fabric and concrete, rather than a national average that may not match your supplier. If you are fencing an irregular lot rather than a straight run, measure the full boundary first with the fence perimeter calculator so the length you feed into this calculator reflects corners and offsets instead of a straight-line guess. Chain link is one of several metal fencing options covered on this site; the broader metal fence calculators hub links to the aluminum, ornamental and ornamental post tools for projects that call for a different look or a taller, more decorative result than standard galvanized fabric provides. Working through the post calculator, the fabric calculator and the cost calculator together, all against the same run length, is the most reliable way to avoid the two most common chain link estimating mistakes: skipping concrete at terminal posts and using wood spacing instead of the wider interval chain link is built for.

Height and fabric gauge are the two inputs that do not change the post math here but do change the price, and it helps to settle them before ordering rather than after. Residential chain link commonly runs 4 to 6 feet, with 8 foot runs used for sport courts or deer exclusion, and a taller run catches more wind, which is part of why high wind areas often call for tighter post spacing even with the same fabric. Fabric gauge, usually described as 11.5 down to 9 gauge for homes, is a separate decision from height: a lower gauge number means heavier wire that resists bending and costs more, and picking it has no effect on how many posts or how much concrete this calculator returns, only on the price per roll you enter into the cost calculator. Terminal post hardware, including tension bands and brace bands, scales with the number of corners and ends rather than with height or gauge, so a short run with several corners can need more terminal hardware than a longer straight run with just two ends. Working out height and gauge first, then running the numbers through this calculator and the fabric calculator together, keeps the whole estimate internally consistent before you request pricing from a supplier.

常见问题

为什么默认的柱间距是 10 英尺而不是 8?

铁丝网片的张力分配方式与木板不同,因此它通常在更宽的间距(通常为 10 英尺)上运行,而不会下垂。您仍然可以在计算器中设置所需的任何间距。

铁丝网还需要混凝土基础吗?

是的,特别是在角柱、端柱和门柱处,它们承受拉伸网片的张力。无论材料如何,该计算器都以相同的方式计算每个立柱的混凝土。

一个铁丝网柱需要多少袋混凝土?

与任何栅栏柱相同的体积数学:孔直径和深度设置体积,并且该计算器将其转换为 50、60 和 80 磅的袋子计数。一个典型的 10 英寸 x 24 英寸孔需要大约 2.5 到 3 袋 60 磅的混合物。

铁丝网围栏上是否需要顶部横梁?

在住宅铁丝网围栏上通常是的:顶部横梁将立柱绑在一起并保持网片边缘笔直。底部的张力线是网片下方常见的伴侣。

铁丝网使用什么尺寸的立柱?

住宅铁丝网通常使用 Schedule-40 管道:中间立柱约 1.5 至 1.875 英寸,具有较重的端子和角柱。许多系统规格为 2 英寸中间立柱;请遵循制造商表了解您的高度和间距。

铁丝网围栏有多高?

住宅高度通常为 4 至 6 英尺,8 英尺可用于运动或排除鹿。较高的网片会吸引更多的风,因此请确认您选择的高度的立柱尺寸和间距。

铁丝网多少钱?

铁丝网通常是常见选项中每线性英尺最便宜的材料,确切的数量取决于高度、网片规格和当地价格。在此计算器中输入您自己的单价,以获得与您的数字相关的总价。

我应该使用哪种规格的铁丝网片?

住宅网片的规格通常为 11.5 至 9 号,规格越重(数字越小),成本越高,抗损坏能力也越好。对于宠物或安全围栏,中规格是一个很好的平衡;计算器的材料数学不取决于规格,但您的报价会。
