Thank the lord I dont work in California.
Pennsylvania is easy.
IRC and there are I think 2 revisions at the state level.
California Building Code?
Doesn't mean anything to me....
So, what did ya find out, just in case I ever get a rail to do in Memphis... in between trips to the Rendezvous. Winterlude, Winterlude, my little daisy,
Winterlude by the telephone wire,
Winterlude, it's makin' me lazy,
Come on, sit by the logs in the fire.
The moonlight reflects from the window
Where the snowflakes, they cover the sand.
Come out tonight, ev'rything will be tight,
Winterlude, this dude thinks you're grand.
actually i didn't yet... i was doing some layouts... my steel comes 20ft... so i like to design for best use... least waste...
not that i ever toss out a steel drop... and they always seemed to get used... which is another great thing about steel & welding there really is pretty close to zero waste... and even that if tossed into a drum can be sold for scrap... 55gal drum of pure junk steel drops could be worth $200
i always find uses for 2-3" long angle iron drops... i have an electric over hyd. hole punch that with 2 holes in 5 seconds turns em into great mounting brackets...
anyway... did some layouts... and 8 of my rails return/trans into being stair hand rails so at 40" rail height it makes it "look" more "right" haven't settled on any one design... and not sure how many will be alike... "alike" speeds production but... being different... i get to take artistic liberties.... both have a place... sometimes material "on hand" wins the design...
I've been real consistant in materials just used in different ways... so... until i start cutting & burning metal... even i don't know final design.. keeps me interested
way more info than you asked for i know :)
p
I've always found your use of materials to be more than interesting... the more info, the more interesting.Is your project considered residential, or commercial? And how do you get to be artistic with the inspections dept? Liabitility's not a concern?And, where's the pics of this place? Winterlude, Winterlude, my little daisy,

WOW ! 42" on a balcony rail is awfully high , very uncomfortable for most people to grab . I have built three stairs this year with balcony rails set around 37" . They passed . We will see what happens . Thanks for the info
Joe
A guard rail is different than a handrail, no?
A guard rail surrounds a deck, or balcony, or open stairwell.....whereas a handrail goes up with a set of stairs.
A hand rail should be lower than 42", so that it is comfortable to grab. Especially for children.

You are correct . Your comment made me think of the commercial jobs I have done where I have run both a guard rail and a grab rail , although code does not require a grab rail on a balcony . I do think it is a shame to require a 42" min height on a balcony for residential because it can make a less than attractive transition from rake rail to balcony rail/guard rail . ( rails are drastically different heights where they meet post) I most always set my balcony heights at least 37" from finish floor and they are very comfortable and safe .
I agree that it always looks nicer when balcony and handrails are set, and meet at the same height....but with children of my own, I have come to learn that a lower guard rail is almost asking for trouble as the kids tend to climb anything they can reach the top of.
I tend to make the best of a "bad" situation and set handrails at minimum heights and guardrails higher. I find it more pleasing to the eye if they are further apart, rather than ALMOST in line, which can appear to be a mistake.
Beware the bikini clad female.

Understanding the reason for the 42" height makes it more palatable.
36-37" high railings put the majority of the body mass above the railing height. A slip , bump or dumb move puts you over the railing much easier at the lower heights than at 42" and higher. The lower railing height actually acts as a fulcrum instead of a restraining device.
They can't get your Goat if you don't tell them where it is hidden.
Pretty sure it's 42" on a second story interior railing
42" here
you only get one chance to do it right the first time
Commercial may be different than residential, county different than state, city different from county...
In NC residential, stairs are 30-38", balconies 36"... lotta different no.s in this thread<G>

FYI here in NC commercial and multi family residential guardrails (interior or exterior) need to be 42". As you say though, 1 and 2 family residential is 36".

FWIW. International Residential Code. Guards (railing) Section R312. Min. 30" if required.
International Building Code (commercial) Guards (railing) Section 1012. Min. 42" if required.
Guards required if balcony &/or porch is more than 30" above the finish floor below.
Local codes may vary. Better check.
Correction. Residential code is 36"min, not 30" as I first posted. Sorry about that. Again, it should be 36" min. for residential construction.
National code? What code is that?
You need to first say what state you live in. I'm thinking it's Tenn?
