FORM 10-K FOR THE YEAR ENDED OCTOBER 29, 2005

included in your future filings.

Item 3 - Legal Proceedings, page 21

2. Regarding the lawsuits filed by Bethlehem and National, please
include the name of the court in which the proceeding is pending
and
the date instituted.  See Item 103 of Regulation S-K.

Financial Statements

3. Please include a column showing the changes in the number of
common shares issued, as well as a column showing the changes in
the
number of shares held as treasury stock.

Note 1 - Nature of Business and Principles of Consolidation, page
7

4. You state that for investments in joint ventures and other
entities that do not meet the criteria of a variable interest
entity
you use the equity method of accounting where your ownership is
between 20 percent and 50 percent or where your ownership is more
than 50 percent and you do not have significant influence or
control
over the consolidated entity.  For each entity for which you own
more
than 50 percent and do not consolidate, tell us how you determined
you were not required to consolidate.  Please refer to the
applicable
accounting literature in your explanation.

Note 2 - Summary of Significant Accounting Policies, page 7

5. Please disclose the types of expenses that you include in the
cost
of sales line item and the types of expenses that you include in
the
selling, general and administrative expenses line item.  Please
also
disclose whether you include inbound freight charges, purchasing
and
receiving costs, inspection costs, warehousing costs, internal
transfer costs, and the other costs of your distribution network
in
the cost of sales line item.  With the exception of warehousing
costs, if you currently exclude a portion of these costs from cost
of
sales, please disclose:
* in a footnote the line items that these excluded costs are
included
in and the amounts included in each line item for each period
presented, and
* in MD&A that your gross margins may not be comparable to those
of
other entities, since some entities include all of the costs
related
to their distribution network in cost of sales and others like you
exclude a portion of them from gross margin, including them
instead
in a line item, such as selling, general and administrative
expenses.

(g) Revenue Recognition, page 9

6. Please provide us with additional information regarding the
change
in your revenue recognition policy related to steel coils.
Specifically, address the following:
* Tell us how your revenue recognition policy prior to the third
quarter of fiscal 2004 complied with Topic 13A of SAB No. 104;
* Tell us whether any raw materials were consigned to you
subsequent
to the third quarter of fiscal 2004 and how you recognized revenue
related to these raw materials; and
* Tell us how your revised revenue recognition policy beginning in
the third quarter of fiscal 2004 complies with Topic 13A of SAB
No.
104.

liability.  See paragraph 14(b) of FIN 45.

(i) Self Insurance, page 9

8. Please disclose the extent of your self-insurance in each area
that you are self-insured.  Please also disclose whether or not
you
have excess loss insurance and, if so, the amounts at which this
insurance coverage begins in each area.

Note 6 - Long-Term Debt, page 13

9. Please tell us how you accounted for the 2.125% convertible
senior
subordinated notes, including what consideration was given to the
contingent conversion features and whether any beneficial
conversion
features existed.  Your explanation should refer to the accounting
literature considered and relied upon to determine the appropriate
accounting.




Note 9 - Operating Lease Commitments, page 17

10. Please disclose how you account for (a) step rent provisions
and
escalation clauses and (b) capital improvement funding and other
lease concessions, which may be present in your leases. Paragraph
5.n. of SFAS 13, as amended by SFAS 29, discusses how lease
payments
that depend on an existing index or rate, such as the consumer
price
index or the prime interest rate, should also be included in your
minimum lease payments.  If, as we assume, they are taken into
account in computing your minimum lease payments and the minimum
lease payments are recognized on a straight-line basis over the
minimum lease term, the note should so state.  If our assumption
is
incorrect, please tell us how your accounting complies with SFAS
13
and FTB 88-1.

11. Please include the disclosures required by paragraphs 16.c.
and
d. of SFAS 13 regarding your operating leases.

Note 13 - Net Income Per Share, page 20

12. Please tell us how your current treatment of the 2.125%
convertible senior subordinated notes in arriving at your net
income
per share amounts complies with EITF 04-08.  Your explanation
should
refer to the specific paragraphs of the EITF that led you to
determine that your treatment is appropriate.

Note 18 - Business Segments, page 21

13. Please disclose the types of amounts included within corporate
assets for each period presented, and disclose why these amounts
were
not allocated to the other reportable segments.  See paragraphs 31
and 32 of SFAS 131.

Management`s Discussion and Analysis of Financial Condition and
Results of Operations, page 27

Results of Operations for Fiscal 2005 Compared to Fiscal 2004,
page
30

14. Please discuss the business reasons for the changes between
periods in cost of sales.  In doing so, please disclose the amount
of
each significant change in line items between periods and the
business reasons for it.  In circumstances where there is more
than
one business reason for the change, attempt to quantify the
incremental impact of each individual business reason discussed on
the overall change in the line item.  Please show us what your
revised MD&A for 2005 as compared to 2004 will look like.  See
Item
303(a)(3) of Regulation S-K and Financial Reporting Codification
501.04.

Contractual Obligations, page 35

15. Please revise your table of contractual cash obligations to
include the estimated interest payments on your debt.  Because the
table is aimed at increasing transparency of cash flow, we believe
these payments should be included in the table.  Please also
disclose
any assumptions you made to derive these amounts.
